refactor: 🏷️ Add symbolicEqual function to Typescript definitions

[juancodeaudio]

I've added the symbolicEqual function to the Typescript definitions in 'types.d.ts' inside the MathJsChain interface.

Closes #2960

Thanks Juan!

We need to define the function symbolicEqual twice: once the regular definition, and once for the chained definition. Can you add both definitions? Maybe easiest is to look up the two definitions of the function equal for example to understand the idea.

Also, when you run npm run lint you can check if there are linting issues, and most of them can be fixed automatically by running npm run format.

@juancodeaudio did you see my last comment?

[juancodeaudio]

Sure, i'll work on that!!

@josdejong I just added both definitions. As you said, I followed how the "equal" function is defined. Let me know whether it's complete now

[josdejong]

Thanks for the update, this is close. The function doesn't accept MathType | string though, but MathNode | string, can you change all occurrences of that? And since the function does not support matrices, it will always return a boolean and not MathCollection.

@josdejong thank you for the feedback. I already changed those types, hope it's ok now.
