Codespell renders github variables as path, rendering it useless in actions with excluded_files option

[Int-Circuit]

Description of the bug

When using variables to specify path of excluded_files, the action renders variables as path which fails the step

Expected behaviour

The action correctly processes the variable and uses the correct path
