Bump version to 0.1.10 (#9360 )

Add paths to toml parse errors (#9358 )
**Summary** Previously, the information which toml file failed to parse was missing in errors. **Before** ```console $ ruff check /home/konsti/projects/datasett ruff failed Cause: TOML parse error at line 12, column 8 | 12 | python "=3.9.2" | ^ expected `.`, `=` ``` **After** ```console $ ruff check /home/konsti/projects/datasett ruff failed Cause: Failed to parse /home/konsti/projects/datasett/datasett-0.0.1.tar.gz/datasett-0.0.1/pyproject.toml Cause: TOML parse error at line 12, column 8 | 12 | python "=3.9.2" | ^ expected `.`, `=` ``` I avoided pulling in `fs_err` just for this case.

 # Breaking Changes

+## 0.1.9
+
+### `site-packages` is now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
+
+Ruff maintains a list of default exclusions, which now consists of the following patterns:
+
+- `.bzr`
+- `.direnv`
+- `.eggs`
+- `.git-rewrite`
+- `.git`
+- `.hg`
+- `.ipynb_checkpoints`
+- `.mypy_cache`
+- `.nox`
+- `.pants.d`
+- `.pyenv`
+- `.pytest_cache`
+- `.pytype`
+- `.ruff_cache`
+- `.svn`
+- `.tox`
+- `.venv`
+- `.vscode`
+- `__pypackages__`
+- `_build`
+- `buck-out`
+- `build`
+- `dist`
+- `node_modules`
+- `site-packages`
+- `venv`
+
+Previously, the `site-packages` directory was not excluded by default. While `site-packages` tends
+to be excluded anyway by virtue of the `.venv` exclusion, this may not be the case when using Ruff
+from VS Code outside a virtual environment.

-# flake8-to-ruff
-
-Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
-[Ruff](https://github.com/astral-sh/ruff).
-
-Generates a Ruff-compatible `pyproject.toml` section.
-
-## Installation and Usage
-
-### Installation
-
-Available as [`flake8-to-ruff`](https://pypi.org/project/flake8-to-ruff/) on PyPI:
-
-```shell
-pip install flake8-to-ruff
-```
-
-### Usage
-
-To run `flake8-to-ruff`:
-
-```shell
-flake8-to-ruff path/to/setup.cfg
-flake8-to-ruff path/to/tox.ini
-flake8-to-ruff path/to/.flake8
-```
-
-`flake8-to-ruff` will print the relevant `pyproject.toml` sections to standard output, like so:
-
-```toml
-[tool.ruff]
-exclude = [
-    '.svn',
-    'CVS',
-    '.bzr',
-    '.hg',
-    '.git',
-    '__pycache__',
-    '.tox',
-    '.idea',
-    '.mypy_cache',
-    '.venv',
-    'node_modules',
-    '_state_machine.py',
-    'test_fstring.py',
-    'bad_coding2.py',
-    'badsyntax_*.py',
-]
-select = [
-    'A',
-    'E',
-    'F',
-    'Q',
-]
-ignore = []
-
-[tool.ruff.flake8-quotes]
-inline-quotes = 'single'
-
-[tool.ruff.pep8-naming]
-ignore-names = [
-    'foo',
-    'bar',
-]
-```
-
-### Plugins
-
-`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
-configuration file.
-
-For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
-will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
-checks.
-
-Alternatively, you can manually specify plugins on the command-line:
-
-```shell
-flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
-```
-
-## Limitations
-
-1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
-    ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
-    configuration options that don't exist in Flake8.)
-1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
-    codes from unsupported plugins. (See the
-    [documentation](https://docs.astral.sh/ruff/faq/#how-does-ruff-compare-to-flake8) for the complete
-    list of supported plugins.)
