feat: Update CDN bundle & loader docs

[mydea]

I noticed we had a few incorrect things in our loader/cdn docs:

1. Instructions to get to loader settings where not correct anymore
2. Instructions about es5 bundles where incorrect (they no longer exist)
3. We missed a few bundles/I updated some things to be more up-to-date, including feedback as well.

Potential bug: The 'Full Bundle' script tag has a mismatched integrity hash in loader.mdx, causing SRI failures that will prevent the Sentry SDK from loading for users.

• Description: The script tag for the 'Full Bundle' in loader.mdx specifies bundle.tracing.replay.feedback.min.js as the source. However, the integrity attribute is generated using the checksum for bundle.tracing.replay.min.js via the @inject packages.checksum helper. This mismatch will cause browsers to fail the Subresource Integrity (SRI) check and refuse to execute the script. As a consequence, users copying this snippet will have the Sentry SDK fail to initialize silently, resulting in a complete loss of error monitoring, tracing, and replay functionality.

• Suggested fix: Update the @inject packages.checksum call within the integrity attribute to use the correct filename, bundle.tracing.replay.feedback.min.js, ensuring it matches the src attribute of the script tag.
