Introducing configuration presets!

[lowlighter]

With 3.19 (currently available on @master/@main branch), config_presets option will let you share configurations with other people and/or reuse same settings across different repositories and workflows through YAML presets.

No need anymore to configure all 200+ options manually, almost any default value of options supported by metrics can be overriden through this feature.

Example: a simple preset that enable 📅 isocalendar set it to full-year by default

schema: v1
with:
  plugin_isocalendar: yes
  plugin_isocalendar_duration: full-year

Example: using a preset in a workflow

- uses: lowlighter/metrics@latest
  with:
    config_presets: https://raw.githubusercontent.com/user/repo/main/preset.yml
    # plugin_isocalendar: yes
    # plugin_isocalendar_duration: full-year

For convenience, presets published on the @presets branch can be included using their identifier prefixed by an @:

- uses: lowlighter/metrics@latest
  with:
    config_presets: "@lunar-red, @ocean-blue"

If you have some interesting presets and/or themes you would like to share, feel free to open a pull request on @presets branch 👍 !

This feature is based on @spenserblack's idea from #794
