[backport] Beamer template missing options

[cderv]

Important

PR for 1.7

backport for #12680

@gordonwoodhull it would be good to be included if we do a patch release. I am making the PR to run the test.

Left to do

• Add to changelog
• Re-build schema files

[cderv]

@gordonwoodhull I let you merge

It needs to run quarto dev-call build-artifacts to generate the new schema files, but maybe this is better to do it on the stable branch right before release ?

I let you decide.

THanks !

Just FYI, in 1.7 that should still be quarto build-js.
