[lovisaberggren]

The Babel plugin babel-plugin-transform-import-meta currently declares @babel/core@"^7.10.0" as a peer dependency, which causes ERESOLVE errors when installing alongside @babel/core@8.x.

There are two PRs open on the plugin repo (javiertury/babel-plugin-transform-import-meta#33, javiertury/babel-plugin-transform-import-meta#32) to update the Babel dependencies to 8.x, we can wait for these to be fixed before upgrading Babel to 8.x on our side. 7.x is still maintained so there is no rush to upgrade.

An alternate would be to get rid of the babel-plugin-transform-import-meta, however for our Jest tests we would need to switch Jest to native ESM mode. This is still experimental and could require a heaver lift/refactor.

Closing this for now and we can check in with the babel-plugin-transform-import-meta next time.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
