feat(babel-plugin-jsx-pragmatic): migrate to typescript

[G-Rath]

What:

Migrates @emotion/babel-plugin-jsx-pragmatic to TypeScript.

Why:

Part of #2358

How:

Renamed the js file to ts, and made changes to make TS happy.

Checklist:

• Documentation
• Tests
• Code complete
• Changeset

I've not converted the tests because I don't know how to handle babel-tester since it's apparently coming in as some magical workspace thing (I've not worked with workspaces a lot 😅).

I'm sure there will be a way to tell TypeScript that it exists, but that probably will need either a type definition written or the package converted to TypeScript, so have left it for now.

I'll be making a few follow-up PRs to DefinitelyTyped that'll remove the need for some of the types, but they probably won't land for at least a month.

btw this should also allow me to do @emotion/preset-css-prop, since that uses this package

@G-Rath Looks good. Was there any progress on getting some of these types into DefinitelyTyped so they can be removed from the Emotion code?

Edit: I see you now that you got the PluginPass stuff merged in DefinitelyTyped. Could you update this PR to take advantage of that change? Thanks.

Edit 2: Ideally the tests for babel-plugin-jsx-pragmatic should be converted to TypeScript too for this change. The code for babel-tester is in scripts/babel-tester/src/index.js. If you change that file to .ts it should "just work".

Ideally the tests for babel-plugin-jsx-pragmatic should be converted to TypeScript too for this change.

I don't mind doing converting babel-tester & the tests for this to TypeScript, but would prefer to address it in another PR if possible because I think it is a larger change: it's types will probably need some crafting, and at the least babel-check-duplicated-nodes doesn't have types so someone will need to define them.

[srmagura]

OK, since it is a bigger change, doing it in a separate PR is fine 👍

@Andarist I believe this is ready to be merged.

sweet, sweet little lies 😅

@G-Rath I've prepared babel-tester migration here: #2688
