Fix pendulum.parse('now', tz='...') ignoring the time zone

• Added tests for changed code.
• Updated documentation for changed code (nothing to update - as far as I can tell this isn't mentioned in it).

Previously, using "now" with pendulum.parse short-circuited all other parsing logic (expected), including the time zone (not expected).

Example using the latest release:

>>> import pendulum
>>> pendulum.__version__
'2.1.2'
>>> pendulum.parse("2023-04-04", tz="America/Los_Angeles").format("z (Z)")
'America/Los_Angeles (-07:00)'
>>> pendulum.parse("now", tz="America/Los_Angeles").format("z (Z)")
'Etc/UTC (-00:00)'

The same example after this PR:

>>> import pendulum
>>> pendulum.__version__
'3.0.0a'
>>> pendulum.parse("2023-04-04", tz="America/Los_Angeles").format("z (Z)")
'America/Los_Angeles (-07:00)'
>>> pendulum.parse("now", tz="America/Los_Angeles").format("z (Z)")
'America/Los_Angeles (-07:00)'

I'll preface saying I'm not a maintainer of this repo, so my approval is only nominal 🙂.

This LGTM, there's a Rust linting error but I don't know if it's related to changes in this PR.

Hi. Sorry for the delays, we are digging ourselves out of the pile of code debt. Could you please rebase your changes with the master branch so we can review and merge them?
