Automatically focus confirm button on confirm page

[Exagone313]

Fixes #2214

This is a regression introduced in commit:
05dc48e

The autofocus attribute was removed unexpectedly in a localization
change.

Additional information:

I had this error when loading the extension locally:

Extension is invalid
Loading locale file _locales/.github/messages.json: Error: Error while loading 'file:///home/exagone/Git/multi-account-containers/src/_locales/.github/messages.json' (NS_ERROR_FILE_NOT_FOUND)

Same with web-ext (without verbosity):

o: installTemporaryAddon: Error: Error: Could not install add-on at '/home/exagone/Git/multi-account-containers/src': Error: Extension is invalid

Temporarily fixed it by adding a symlink from .github to en. I don't know if it's a bug related to my environment or not.

So I tested and it works.

I forked the repo to reintroduce this feature and before opening a pull request, I found this. I do extensive use of this add-on and it's really getting into my head that this property was removed.

Thank you for the contribution 👍

I have held updating this addon on all my systems/profiles until this is merged and published. This disrupts my workflow too much.

Thanks! Running workflow to check and will merge and set up a release.

Spot-check and code looks good.

Thanks for merging it @groovecoder, this is really nice. And thank you for all the effort on this project.

Just to calm down my anxiety, do you know what's the next step for the release? I take a look at the releases and it happens with quite a few months between them. Is there anything we can do to help on this?
