[match] fix match nuke not deleting decrypted files

[revolter]

Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I see several green ci/circleci builds in the "All checks have passed" section of my PR (connect CircleCI to GitHub if not)
• I've read the Contribution Guidelines
• I've updated the documentation if necessary.

Motivation and Context

I noticed that running fastlane match nuke and cancelling it (answering n to "Do you really want to nuke everything listed above? (y/n)") causes the decrypted git repo to remain in the temp folder, which I personally think it's a security issue.

Description

I added an ensure block that deletes it, similar to the runner.rb file.

Testing Steps

Add

gem 'fastlane', git: 'https://github.com/revolter/fastlane.git', branch: 'security/match-nuke-cancel-decrypted-files'

to your Gemfile, and run bundle install to apply the changes.

Then run bundle exec fastlane match nuke development, then press n, and see that a folder like /var/folders/73/rlp8bl_x5lg1vbv1xbz159d40000gn/T/d20221021-22249-cq51af still exists, which contains the decrypted certificates and profiles.
