Allow ARIA label with token support

Thank you for your work on this @iyyappan.govind!

I've opened a MR with the changes from the above patch and made a few changes to ensure that tests still pass and this functionally will still work if the token module is not installed.

Attached is a patch mirroring the MR for patching your own project.

Update patch file with the recent fix to aria label HTML attribute.

Note: Currently, the patch will not apply to the current stable 2.0.3 version of this module. In order to apply this patch to your site/project, you will need to include additional commits/patches that are currently only on the dev branch.

If using composer-patches, update your composer.json with the following in the "patches" config:
