DOC: Add datetime64 example for 'Now' to get the current time - #26477

This fails doctests. You should add a +SKIP directive, like here

File "/tmp/tmpeo8sv853/doc/source/reference/arrays.datetime.rst", line 93, in doc/source/reference/arrays.datetime.rst
Failed example:
    np.datetime64('now', 'ms')
Expected:
    numpy.datetime64('2024-05-18T18:02:42.000')
Got:
    np.datetime64('2024-05-18T18:58:30.000')

@mattip Thank you so much, I have made the changes, this is my first open source contribution at PyCon US 2024 Pittsburgh.

@mattip , Can we close this ?

Just FYI, it's always a good idea to submit features on a branch other than your main branch - one reason why is that maintainers often push minor suggestions to the PR to make things quicker; however this is not possible for PRs that originate from the main branch on your fork. Just a little nugget for next time!

I will go ahead and close as requested!

@rossbar I think maybe @Shreyjaradi meant "Can we merge this?" ?

Issue #10003 is still open and the "now" and "today" strings remain undocumented.
I came across the problem and started implementing a fix before I found this PR.
