Docs state extracting from code supports wildcards, but it does not

[haf]

Describe the bug
According to the docs, I can feed intl_translation:extract_to_arb a wildcard path:

This supports wildcards. For example, to extract messages from a series of files in path lib/**/*.dart, you can run

https://pub.dev/packages/intl_translation#extracting-and-using-translated-messages

This is directly false as it's more of a guide on how to use some (not all) shells on some (not all) operating systems. For you to state that the software supports wildcards, the process that is your software must be able to take in wildcards (the process that is your software will only take in a set of relative paths without wildcards by following the implicit intent of the documentation).

To Reproduce

Follow the docs.

System info

You could merge #528 - there was a PR back in 2019 which seems to have been forgotten. Note: I haven't reviewed the code of the PR.

(Yes, yes, yes! But this is a nitpick only! — No, it's actually not; I'm running my commands via Taskfiles that don't support wildcard expansion (quite sanely) — the expectation is that I can type the exact program inputs without knowing the escape rules for my particular shell when codifying commands)
