add possibility to overwrite filter output

[Fuzzyma]

Sometimes I want to run my code no matter what the filter returns. Atm I have to write this for every step:

if: steps.changes.outputs.filter1 == 'true' || someOverwriteCondition == 'true'

That is very cumbersome. It would be cool to have a parameter overwrite to set all filters to true:

with:
  filters:
    ...
  overwrite: ${{ someOverwriteCondition }}
