refactor(resolve): replace read-pkg-up with escalade

[TrySound]

Summary

Ref https://packagephobia.com/result?p=read-pkg-up https://packagephobia.com/result?p=escalade

Read-pkg-up package is quite big and have a lot of dependencies.
It also handles cases not necessary for jest. Beautiful JSON parsing
errors are not relevant and can be replaced with builtin JSON.parse.

Test plan

Not sure about this. Looks like es modules support was not covered by tests.

[TrySound]

Aha, looks like testing on 13.2 is not a good idea. Native ESM support is broken until 13.7. The issue is the same as in many packages with es modules support.

Error: No valid exports main found for '/.../jest/node_modules/yargs'

Thanks! Left some inline comments. In addition to those, could you add a changelog entry?

[SimenB]

thanks!

for anyone stumbling across this issue due to this error:

Error: No valid exports main found for '/.../jest/node_modules/yargs'

you need to update the version of node that you're using to >=13.7

[SimenB]

Let's revert and re-land for Jest 27. At that point we'll drop support for Node 13 anyways (13 has been EOL since June).

[TrySound]

@SimenB Are you gonna revert and escalade and yargs as well? Are you sure any more dependencies won't add it?

[SimenB]

yarn why escalade only points to browserlist now, which we have as a dev dep from babel, so should be good
