fix: escape function path regex chars

[Skye-31]

Closes #1685

Currently, if you have a file such as functions/*.ts, pages attempts to run path-to-regex on this, and this will fail, as it assumes it's a regex character (it shouldn't be). This results in an Unexpected MODIFIER at 1, expected END. error. This PR correctly escapes these characters to solve the issue (confirmed fix from Alastair)

Hey Skye! Thanks for putting this together.
Not quite sure I understand what this is fixing. Some files have * in them?

Would you mind adding some test cases before this change (with working paths) to ensure we don't break existing functionality? Then we could add this change with additional tests showing the old + additional paths work.

Edit: I see now we have some tests - per our convo, maybe add some tests with _ and -, and any other character's folks might use. Thanks!
