@babel/register: add typescript to default extensions -> .ts,.tsx

## Feature Request

- [x] I would like to work on this feature!

**Is your feature request related to a problem?**

Currently when one uses typescript as language and type checking and babel for transpilation and with that tooling usage is needed, for instance with mocha or uvu etc, there is no way to use `mocha --register @babel/register my-tests.spec.ts`

**Describe the solution you'd like**

It would be nice to add typescript to default set off extensions.

With that set, we would need to add a check if `preset-typescript` is present and if it's not, we should error out with appropriate information for user - `"Hey looks like you wanna transpile typescript but your config is missing 'preset-typescript' preset"`.

**Describe alternatives you've considered**.

Currently we need to use `ts-node` which feels quite redundant especially when all transpilation and tooling is powered by babel.

Start at the @babel/register entry point and inspect how its default extensions are defined. Check how preset-typescript configuration is detected, then verify that .ts and .tsx registration works and that a missing preset produces the requested guidance; the issue does not name a file or test to run.
