Support typings for Jest v27

[billyjanitsch]

What:

@emotion/jest is currently only compatible with Jest 26 when using TypeScript because it optionally peer-depends on @types/jest@26:

emotion/packages/jest/package.json

Lines 26 to 27 in 4c7b6de

	"peerDependencies": {
	"@types/jest": "^26.0.14",

This PR widens the peer dependency range from ^26.0.14 to ^26.0.14 || ^27.0.0 such that both 26 and 27 are supported.

Why:

See above.

How:

See above.

Yes, this change will remove the peer dependency install error that currently prevents you from running npm i @emotion/jest@11.3.0 jest@27 @types/jest@27.

@billyjanitsch if your are busy we caise another pr, rebased with master?

There's no reason to rebase the branch now. It can be done by a maintainer before merge. This PR is just awaiting review. Please be patient as this project is a volunteer effort.

@Andarist whenever you have a moment, could you let me know if you see anything that prevents this from being an easy merge? I don't believe there were any changes to the v27 typings that would affect @emotion/jest. But if you have any concerns, I'm happy to look into them to reduce the burden for you.

Hard to assess - we don't have a lot of actual dependency on those types so hopefully this shouldn't be problematic. We'll see after a release, in the worst-case scenario we'll have to do some minor adjustments to make it work with both (that's the hope, at least 😅 ).

We use @emotion/jest with @types/jest v27 for few weeks already, No issues so far beside peer warning during install.
