chore(build): Lower size-limit action limits

[Lms24]

This PR lowers our size-limit maximum bundle size limits. Previously, most of them were set to rather arbitrary high numbers (100Kb mostly). With these adjustments, we lower them to +10Kb of each entry's current size. The reason for doing this is to catch problems with tree shaking or unexpected large bundle size hits more reliably. As outlined in #6508 (comment), we could for instance catch the Replay integration being wrongfully included in to our standalone Browser SDK CDN bundles.

In case the limits are hit, the "Size Limit" CI job will fail.
