Stability testing with ADE repo

[PauliusKu]

task for code text change testing with ADE repo.

Current goal is to reach less than 1%

[PauliusKu]

328 failing tests so far (4396 passing)

[PauliusKu]

266 with current develop

[PauliusKu]

174 with tree-sitter 0044 (3.68% failed)

[PauliusKu]

After making this change #267 the number of errors was reduced to 91 (1.93%)

[PauliusKu]

82 with tree-sitter 0045

TODO list:

1. Improve framework to allow easier debugging (write failing test results to files)
2. Go through all existing issues and analyze them. Categorize by issue's source: Tree-Sitter parser error, Tree-Sitter parsing incorrect, Formatter bug, else ...

TODO part 2:

1. In addition to before & after files, create a simple list (like ignore file) for failing test, so we could use it as input in known issues file (see part 2).
2. Add known issues file, so that framework might not show some known failures
3. Add full project relevant file paths to the file names used while testing, because in a code base there might be multiple files with same name but different location.
4. Improve the testing framework and attach it to GitHub pipeline as sort of regression tests.
