Describe the changes you're proposing

The installation of textfile collectors is currently not part of testing which probably resulted in the installation being broken without realizing. This PR fixes template and installation issues regarding the textfile_collectors state and the provided collectors in this repository.

Pillar / config required to test the proposed changes

When running the kitchen tests, enable a collector in the pillar, and test e.g. debian-11-3004-0-py3

prometheus:
  exporters:
    node_exporter:
      textfile_collectors:
        ipmitool:
          enable: true

Debug log showing how the proposed changes work

Documentation checklist

• Updated the README (e.g. Available states).
• Updated pillar.example.

Testing checklist

• Included in Kitchen (i.e. under state_top).
• Covered by new/existing tests (e.g. InSpec, Serverspec, etc.).
• Updated the relevant test pillar.

Additional context

Due to pillar key prometheus:exporters:node_exporter:textfile_collectors_dependencies being set to [] in the test pillar data, it overwrites the provided values for Debian in osfamilymap.yaml. To fully test this PR all OS families should declare the necessary textfile collector dependencies and the key should then be removed from the test pillar data.

Hi, thanks for PR. There are issues with commit messages, see https://github.com/conventional-changelog/commitlint/#what-is-commitlint so maybe fix/squash commits. i.e. fix(textfile): corrected the textfile collector installation
