docs(contributing): using vscode on windows (#29257)

Issue number: N/A

---------

<!-- Please do not submit updates to dependencies unless it fixes an
issue. -->

<!-- Please try to limit your pull request to one type (bugfix, feature,
etc). Submit multiple pull requests if needed. -->

## What is the current behavior?
<!-- Please describe the current behavior that you are modifying. -->

Developers on a Windows environment using VS Code will experience an
issue when using prettier, where files will be tracked as modified even
though they have no actual diffs.

This is due to differences in how Unix based operating systems and
Windows treat carriage returns.

## What is the new behavior?
<!-- Please describe the behavior or changes that are being added by
this PR. -->

- Updates the contributing guide to educate developers using VS Code on
how to configure their local environment to not track additional diffs
when formatting the codebase.

## Does this introduce a breaking change?

- [ ] Yes
- [x] No

<!--
  If this introduces a breaking change:
1. Describe the impact and migration path for existing applications
below.
  2. Update the BREAKING.md file with the breaking change.
3. Add "BREAKING CHANGE: [...]" to the commit description when merging.
See
https://github.com/ionic-team/ionic-framework/blob/main/.github/CONTRIBUTING.md#footer
for more information.

## Other information

<!-- Any other information that is important to this PR such as
screenshots of how the component looks before and after the change. -->

This is the same documentation that exists on the ionic-docs repository
for the same reason. I've applied co-authored-by credit to Netkow for
his wonderful contribution to that documentation.

+## Using VS Code on Windows
+
+To contribute on Windows, do the following:
+
+- Configure VS Code to read/save files using line breaks (LF) instead of carriage returns (CRLF). Set it globally by navigating to: Settings -> Text Editor -> Files -> Eol. Set to `\n`.
+
+  - You can optionally use the following settings in your `.vscode/settings.json`:
+    ```json
+    { "files.eol": "\n" }
+    ```
+
+- Check that the Git setting `core.autocrlf` is set to `false`: run `git config -l | grep autocrlf`. Switch it to false using: `git config --global core.autocrlf false`.
+- If you've already cloned the `ionic-framework` repo, the files may already be cached as LF. To undo this, you need to clean the cache files of the repository. Run the following (make sure you stage or commit your changes first): `git rm --cached -r .` then `git reset --hard`.

 1. Run `npm run lint` to lint the TypeScript and Sass.
 2. If there are lint errors, run `npm run lint.fix` to automatically fix any errors. Repeat step 1 to ensure the errors have been fixed, and manually fix them if not.
 3. To lint and fix only TypeScript errors, run `npm run lint.ts` and `npm run lint.ts.fix`, respectively.
