libunistring 1.2

Created with brew bump-formula-pr.

mapnik was already fixed in #164246. So macOS is good, just waiting on self-hosted Linux.

@p-linnane Linux job marked as failed to start, needs a rerun on it if it's possible to get only it I guess?

[Porkepix]

Still needs a rerun of the Linux job alone if possible, or a full long build rerun otherwise.

@p-linnane Looks like Linux dependencies testing again acted weird here…

[p-linnane]

I kicked off a new run, but now the Linux job will need to wait for the pcre2 PR to finish.

[Porkepix]

@p-linnane Then waiting for the self-hosted slot, maybe #164670 can run in-between, or #163651 if you think the recursive dependencies skip would means the self-hosted one ins't needed anymore? (Unless you think nobody would be around firing that one when pcre2 or the other ones finishes and that it's a priority).

[p-linnane]

I'm going to let this run, and then I can remove the long-timeout label after macOS is done and throw it on one of those. This one can sit and wait for just self-hosted Linux.
