chore(gatsby): convert component-data-dependencies to typescript

[Kornil]

Convert src/redux/reducers/component-data-dependencies.ts and test file to TypeScript.

There is one change that can possibly affect production
In src/redux/reducers/component-data-dependencies.ts the action CREATE_COMPONENT_DEPENDENCY was referencing a payload.id in line 19, 20, 31, 32. I found the key to not be used in the action itself, so I removed it. Let me know your opinion, I haven't seen it used.

This should be fine - it seems like legacy code that originally was added in #1503, but feature later on was removed as part of v2 release

Thank you for the tough review @pieh! Added all suggestions, and some.

I removed the number type from nodeId and fixed the tests to reflect that. Also removed type casting in tests for optional chaining and removed casting from reducer file for the preferred non-null operator.

this is so weird that TS is not smart enough to know that this for sure exists given the check above it, but 🤷‍♂️

Awesome! Thank you so much @Kornil - will just wait for CI tests to run again after one small small change (missed one string | number -> string change after your latest changes, so I went ahead and applied it)
