Temporarily relax biome setup for v4

[pfferrari]

What I did

Modified the biome setup to disable several rules and applied a little bunch of changes to the code to let the library raise a lower amount of linting errors. The idea is that we are moving to a new major version of the library and we have not in plan to make big changes to the v4 version to avoid the need of refactoring and retesting a big amount of stuff that should be upgraded to fulfill the standard strict linting rules in a project that is going to be upgraded.

The PR is still not able to pass the biome checks because it is blocked by 8 final issues that I left to be checked together because they are related to some unused punctual ignore rules with comments by Ale that in case could be removed being actually covered by my updated permissive biome setup. I don't know if we care about the comments so I waited for your check to remove them.
