We currently template new reST to be re-parsed after the plot is created, but incorrectly copied the `alt` and `caption` values when they were wrapped. Additionally, change `figmpl` to use Sphinx/docutils' tag creation functions. These functions correctly escape attributes and so fixes invalid HTML when alt text contains quotes.

PR summary
We currently template new reST to be re-parsed after the plot is created, but incorrectly copied the
altandcaptionvalues when they were wrapped.In the future, we should probably drop this template and directly create the nodes we need, but I assume that
TEMPLATEis not private right now for the purpose of letting people modify it.Additionally, change
figmplto use Sphinx/docutils' tag creation functions. These functions correctly escape attributes and so fixes invalid HTML when alt text contains quotes. I also dropped some attributes if they were empty (e.g., we no longer getstyle="" class=""if those aren't specified.)For example, this is broken on the dark colour map image which has quoted colour map names in the alt text.
Fixes #29649
