Update install_X in .tmplr.yml

Logic can be updated to use the new matches pipe:

👉 Use matches pipe to check the value of some variable. This pipe returns the given string if it matches the reference string, and returns an empty string otherwise. This is useful for running conditional commands based on some variable:

steps:
  # ...

  - if:
      eval: '{{ some_var | matches: some value }}'
    update: some_file.txt
    else:
      update: some_other_file.txt

  # ...
