Bug fix: Prevent fully defined links [name](link) from being refo…

…rmatted (#10442)

## Summary

Currently fully define markdown links which include ticks are being
reformatted by

https://github.com/astral-sh/ruff/blob/861998612300520f2c18dbc7b8a6226300ceb508/crates/ruff_dev/src/generate_docs.rs#L105-L114

```[`name`](link)``` -> ```[`name`][name](link)```

For example: https://docs.astral.sh/ruff/rules/typed-argument-default-in-stub/

This PR excludes the open parentheses from the regex, so that these types of links won't be reformatted.

## Test Plan

Extended the regression test.
