feat(web): restrict Safari browser support to >= 16.5

Followup of #1348

There are reports that WebWorkers don't work in Nextclade on Safari 16.3.

I was able to confirm that they do work on 16.5, so I am setting this version as the lowest supported. I don't have access to versions lower than that.
