Fix snpeffdb output to not contain broken symlinks

[mvdbeek]

Instead just copy out the actual .bin files.

We have no test coverage for snpeffdb files since those are composite files in disguise, I can test this manually.

Fixes #5647

Tested this manually by downloading https://www.ncbi.nlm.nih.gov/nuccore/KJ660346, building a database for it and then running snpeff on this and input.vcf from the test data folder

linting seems to be false positive for the somewhat odd add_value filter type

This needs to be uploaded manually to the TS then, as reported by the bot.

Independent of that (I don't know if this is true since options_filter_attribute is undocumented) I think that the options and validator tag are redundant.

Also options_filter_attribute is super inefficient and has been marked deprecated.
