Ignore launchSettings.json (#27346)
Ignore launchSettings.json (#27346)

With crossgen2 now moved into this branch, debugging creates a launchSettings.json for local dev command line / working folder we should ignore.

This is controversial as a default setting for VS (https://github.com/github/gitignore/pull/2705). We are not storing required launch config in any launchSettings.json in this repo so should be fine.
