There did not seem to be any particularly slow tests.
How about a way to change the way the test is run?
1. Use `--shard` option of `jest`
* https://jestjs.io/docs/next/cli#--shard
* For example: https://github.com/apache/arrow/pull/36313
2. Use `@swc/jest` instead of `ts-jest`
* https://github.com/swc-project/jest
* It could be about 1.5 times faster when there is no cache of `jest`
3. Keep a cache of `jest` in CI
