[Feature] ability to filter out symlinks from changed files

Is your feature request related to a problem? Please describe.

Currently, tj-actions/changed-files returns a list of changed files, including symlinks.
For example, if I create a new symlink in the repository, it appears in all_changed_files.

In many CI/CD scenarios (linters, tests, build steps), processing symlinks is not useful, since they are just links and not actual source files.

At the moment, there is no built-in way to exclude symlinks from the outputs.

Describe the solution you'd like?

Introduce a new option, for example:

with:
  exclude_symlinks: true

When enabled, the action would automatically filter out all symlinks from the outputs (all_changed_files, added_files, etc.).
