Add Recipe that allows for the removal/negation of gitignore rules.

[Jenson3210]

What's changed?

Added a recipe

What's your motivation?

First iteration of this seems to work well.

Anyone you would like to review specifically?

@timtebeek as discussed

Have you considered any alternatives or workarounds?

FindAndReplaceText is very restrictive on this. This really uses gitignore rules/logic to determine if a change to the gitignore is necessary.

Any additional context

I've added a workaround for openrewrite/jgit#3
In a next iteration, I want to remove this workaround again once jgit is fixed but guessing we will have some longer checks there.
Planning on 2 later iterations:

• removeEmptyGitignoreFile boolean option that removes a file if the last gitignore entry was removed or it only contains comments/empty lines after changes.
• support wildcard filepaths or directories with wildcard as input: This should match all files matching and for each of these files calculate same negations. Instead of iteration over paths variable, we iterate over all files matching the paths wildcard variables.

Checklist

• I've added unit tests to cover both positive and negative cases (A LOT 😄 )
• I've read and applied the recipe conventions and best practices
• I've used the IntelliJ IDEA auto-formatter on affected files

Thanks @timtebeek, did not get the time for the suggestions yet today. Would've done it otherwise :)

About this build failure...
Looks like it got introduced by this suggestion not updating the parameter name but only the variable usage?

Anyhow pushed a change that uses ctx
