Inverse order in CODEOWNERS

[timotheeguerin]

From the doc this seems to be the way to define catch all. Currently we are getting added to all csharp emitter PRs

https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/customizing-your-repository/about-code-owners

Particularly this part

# These owners will be the default owners for everything in
# the repo. Unless a later match takes precedence,
# @global-owner1 and @global-owner2 will be requested for
# review when someone opens a pull request.
*       @global-owner1 @global-owner2
