cli: remove .spec from ts files

[fanatid]

I can be wrong, but can somebody explain to me why .spec required for TypeScript files?

The only reason it would be useful is if the testing framework needed to differentiate test files from regular modules. If this isn't the case, then removing is fine with me.

I'm not an expert in JS tests frameworks but as I understand *.spec.ts / *.test.ts / etc located with the source file which they test. tests directory do not need files with spec/test suffixes. Also, if we do not use TS, any js will be tested while with TS only *.spec.ts -- this does not look equal 🤔
