Chore: Bump up all package versions together whenever any one version changes (#1131)

* Bump up all package versions together whenever any one version changes.

Keeps everything in sync to make it easy to see if you have the correct dependencies.

https://github.com/changesets/changesets/blob/main/docs/fixed-packages.md

* Empty changeset as this changes nothing for the packages them selves

* Bring @rrweb/web-extension version inline with other packages

* separate the extension version from package.json's to avoid errors
