More tests for Finnish 6-dot braille and some fixes

[samimaattaCelia]

Relates to #501
I went through the tests I had made before and compared them with the specification and the Finnish curriculum, so that the tests would cover them well enough.

I also made some fixes to some tests' MathML and the braille output.

If more tests are needed, then I need more information on what kind of tests, since to me these seem to cover pretty well what is expected of the 6-dot braille. It is mainly used for comprehensive school levels of mathematics.

some checks initially failed because of a problem with the "zip" package that MathCAT depends on.
I have rerun them as the authors seem to have fixed it, but now there are failures regarding the Finnish tests it seems?

@samimaattaCelia can you click on the failing tests and see if the logs are helpful to you?

[samimaattaCelia]

Do you mean the tests that are not passing? If so, then the rules need to be changed so the tests pass.

yes, 2 jobs are failing.

I copied part of the log where it shows the failing tests:

A pull request can only be merged if the checks pass, so it it needs to be fixed first. can you see why/how the checks fail?
