Our trusty tests are failing and we'll also want to merge this into main since it's not part of the Assembly v1 update. (I realize this is not always clear since it will eventually end up in the same release. Since this change is unrelated to Assembly v1, this will help keep our git and changelog history clear.)

• Change the base branch with git: git rebase --onto main assembly-v1-update update-tracesSampleRate-sentry. You'll have some merge conflicts. Resolve the merge conflicts in package.json. Then run nvm use && npm i to resolve the merge conflicts in package-lock.json. Commit and push.
• Switch the base branch of this PR: click "Edit" and then use the dropdown under the title of your PR.
• Fix tests: Update the peerDependencies in package.json to match the version change for @sentry/browser
• Fix tests: Update the value of tracesSampleRate found in analytics-shell.test.js
