Add support for proxy lists

[Jo-Byr]

Support proxy lists in the same way as string/number lists

You need to format your commit appropriately so that semantic release can trigger a new release, update the change log and tag it on github for you.

[jourdain]

Looks reasonable otherwise.

Please rework/reword your commit for semantic release

@Jo-Byr can you add an example?
Also your change introduces a difference between the vue2/vue3 implementation. can you add a markdown file in the docs folder to quickly explain the difference between the two implementations? something like vue2_vs_vue3 or else

I only implemented the proxy list support in the vue2 part of trame-simput. Maybe should I convert this PR to a draft PR for the time being and once the vue2 changes are validated I can add them to the vue3 part ?

[jourdain]

Should we merge?

Seems reasonable
