build: Add yarn changelog command

[mydea]

Since I got slightly annoyed about manually sorting the commits, I wrote a small script to automate that for us.

Now, you can just run yarn changelog to get all commits since the last release, alphabetized.

E.g. for the current release it output this:

- build(deps): bump simple-git in /packages/replay/metrics
- build(utils): Add build constant for cdn vs. npm bundles (#6904)
- chore: Upgrade Node to 16.9.0 (#6971)
- chore(deps): bump default node to latest v16 for e2e-tests (#6962)
- ci: Add labels to gitflow PRs (#6997)
- ci: Fix gitflow workflows (#6995)
- ci: Setup gitflow process (#6890)
- ci(deps): bump actions/upload-artifact from 3.1.1 to 3.1.2 (#6994)
- docs(replay): Add changelog entry and migration log for privacy API (#7008)
- feat: Add aria label to breadcrumb attributes (#6955)
- feat(browser): Track if cdn or npm bundle (#6976)
- feat(core): Add Offline Transport wrapper (#6884)
- feat(loader): Add SENTRY_SDK_SOURCE to track loader stats (#6985)
- feat(replay): Deprecate privacy options in favor of a new API, remove some recording options (#6645)
- feat(replay): Move sample rate tags into event context (#6659)
- fix(nextjs): Add isomorphic versions of `ErrorBoundary`, `withErrorBoundary` and `showReportDialog` (#6987)
- fix(nextjs): Don't modify require calls in wrapping loader (#6979)
- fix(nextjs): Don't share I/O resources in between requests (#6980)
- fix(nextjs): Inject client config into `_app` instead of `main` (#7009)
- fix(nextjs): Use Proxies to wrap to preserve static methods (#7002)
- fix(replay): Catch style mutation handling & null events in rrweb (#7010)
- fix(replay): Handle compression failures more robustly (#6988)
- fix(replay): Only call `scope.getLastBreadcrumb` if available (#6969)
- fix(utils): Account for null prototype during normalization (#6925)
- ref(replay): Log warning if sample rates are all undefined (#6959)

You still need to manually remove stuff etc., but it should help a bit.

I think it pans out, I'd put it takes 30 seconds weekly, which gives me 2h - and it only took me 5 min to write this, so I think we're good 😂
