fix: suggest `@sentry/browser:^7.41.0` as peer dependency

[zichongkao]

When building our packaged Electron app, we ran into this error:

Further tracing led us to a recent thread in the sentry-browser repo which indicated that the problem was fixed in a recent version by removing rrweb as a package dependency. This change bumps the use of sentry-browser to include those fixes.

I tested this by running the test suite.
