Allow to run dynamic TypeScript and JavaScript tests (#31499)

First of all thank you for such a fast editor!

I realized that the existing support for detecting runnable test cases
for typescript/javascript is not full. Meanwhile I can run most of test
by pressing "run button":

/>

I can't run dynamic tests:

/>

I was curious whether I can improve it on my own and created this pr. I
edited schemas and added minor changes in `TaskTemplate` to allow to
replace '%s' with regexp pattern, so it can match test cases:

/>

Release Notes:

- Allow to run dynamic TypeScript/JavaScript tests
