This PR prevents `[]` from being sanitized into an empty string and thus
becoming a "valid", clickable file link in the integrated terminal.
Whenever you type `[]` into the terminal and hover over it while
pressing `cmd`, an empty popup appears and the cursor indicates that
this is a clickable element. Once you click on the brackets, the
worktree root is selected and focused within the file picker.

This is because in #2906 support was added for sanititzing file links
like `[/some/path/[slug].tsx]` to `/some/path/[slug].tsx`. In the case
`[]` where an empty string is returned from the sanitation, the string
is considered a valid file path and thus `[]` becomes a valid and
clickable navigation target.
Given that this an edge-case just for this specific one set of brackets
and otherwise no empty strings are matched from the regexes `URL_REGEX`
and `WORD_REGEX`, it seemed that this was the best place to fix this
bug.
Release Notes:
- `[]` is no longer considered a clickable link in the terminal
