runme attempts to access unreadable files or directories

[pastuxso]

I encountered an issue where the runme does not skip unreadable files or directories during processing, leading to a permission denied error. This behavior occurs even when the files or directories should be ignored using the --ignore-pattern flag.

Issue reported on Discord

PR to replicate the issue: #646 https://github.com/stateful/runme/actions/runs/10252402970/job/28362697530?pr=646#step:7:33

It looks like we don't handle os.ErrPermission

runme/pkg/project/project.go

Lines 367 to 370 in 0cf2e62

	err := util.Walk(p.fs, ".", func(path string, info fs.FileInfo, err error) error {
	if err != nil {
	return err
	}

.

This type of error should be handled separately, and if the path is ignored, it should be skipped. @pastuxso would you like to tackle this?

@adambabik, I could fix it. Thank you for your review. 👍🏻
