chore(deps): Update to tiny-bip39 2.0.0 (#3151)

<!-- Thank you for making a PR! Bug fixes are always welcome, but if
you're adding a new feature or changing an existing one, we'd really
appreciate if you open an issue, post on the forum, or drop in on
Discord -->

## Checks
- [x] I am happy for maintainers to push small adjustments to this PR,
to speed up the review cycle
- [x] I have checked that there are no existing pull requests for the
same thing

I don't know why the previous PR
https://github.com/atuinsh/atuin/pull/2643 got auto-closed after a
rebase, so I am re-creating it.
