fix orcidlink for revtex

[p-slash]

This fixed the ORCID links for PRD for me. I am using Revtex4-2 in Overleaf.
In short: The current output, \author[ORCID]{John Doe}, does not work. This change instead outputs \author{John Doe\orcidlink{ORCID}}.

Hi Naim, sorry I missed this (turned out I was not subscribed to mkauthlist GitHub updates despite getting them from some other cosmodesi repos I am not related to).
Did you mean that the current output does not render the ORCID links (indeed, it does not seem to)? Or does it cause compilation errors for you?
On the other hand, some journals may be using the current format for parsing author information; we might want to double-check this.
(The failing check/test is a hard-coded comparison; it can be fixed easily after we figure out the more conceptual issues.)

I thought this would at least affect @paulmartini's mkauthorxml script, but it actually looks like it won't.

The RevTeX author guides don't seem to mention ORCID:

Actually, the ORCID format support was introduced in AASTeX 6.1: https://journals.aas.org/aastex-v6-1-author-guide/ (not mentioned for 6.0 https://journals.aas.org/aastex-v6-0-author-guide/), but still not in RevTeX it seems. So I think the right thing would be to keep the old format for aastex6, but use Naim's change for revtex.

Thank you Naim, and sorry for possibly excessive scrutiny — although it did uncover a subtlety with the affected aastex6 case.
