Use https instead of ssh for schemastore authentication

## Summary

This PR fixes the bug where the generated fix for `EM*` rules would
replace a
triple-quoted (f-)string with a single-quoted (f-)string. This changes
the
semantic of the string in case it contains a single-quoted string
literal. This
is especially evident with f-strings where the expression could contain
another
string within it. For example,

```python
f"""normal {"another"} normal"""
```

## Test Plan

Add test case for triple-quoted string and update the snapshots.

+///
+/// ## Why is this bad?
+/// Mako templates allow HTML and JavaScript rendering by default, and are
+/// inherently open to XSS attacks. Ensure variables in all templates are
+/// properly sanitized via the `n`, `h` or `x` flags (depending on context).
+/// For example, to HTML escape the variable `data`, use `${ data |h }`.
+///
+/// ## Example
+/// ```python
+/// from mako.template import Template
+///
+/// Template("hello")
+/// ```
+///
+/// Use instead:
+/// ```python
+/// from mako.template import Template
