chore: deprecate jest-runner-tsd

[mrazauskas]

I think it is time to deprecate jest-runner-tsd and encourage people to migrate.

---

TSTyche has different API and that might complicate the migration. But it is worth extra effort, because TSTyche can do more:

• it has more matchers;
• test() and describe() helpers;
• can test on different versions of TypeScript;
• easier to setup;
• less to install (only one package, which is only 200kb),
• and more.

---

tsd-lite is deprecated and I do not plan coming back to it. Reasons are mentioned above (;

An alternative could be to wait for necessary APIs exposed directly from tsd. They were planing to do so in tsdjs/tsd#196. That plan is nearly one year old. So far nothing related with code changes have been done. Also note that in the future they plan to publish tsd as ESM only package. That might cause another trouble with integration.

Another problem is @tsd/typescript. Sounds like something goes wrong with it. The install size of current typescript@5.5.2 is 20.8MB, but @tsd/typescript@5.5.2 is 34.7MB. That’s almost double!

It can stay as is. All versions of tsd-lite are deprecated for some time. So users see the message anyways.
