fix: lint added/modified files only (#26)

# Description

Makes no sense to always validate all files. It's enough to validate the
added/modified files only. This PR configures the `dorny/paths-filter`
action to

- list added/modified files only
- configures the actions for markdown, workflows and yaml to process
these files only

# Verification
