fix: simplify transform RegExp #10207
Conversation
Before
```
"^.+\\.[t|j]sx?$": "babel-jest"
```
After
```
"\\.[jt]sx?$": "babel-jest"
```
RegExp's `[]` doesn't need `|`, in fact, it adds it to the character list it looks for (`/[t|j]/.test('|') === true`). Also since we care only about the suffix, no reason for `^.+`.

Thanks! Should we update any code as well? E.g. https://github.com/facebook/jest/blob/e818dca70b1d314714a98e7ad79e8b73f1af9ec2/packages/jest-config/src/constants.ts#L11 and potentially other places
