Brackets missing in HGVS Protein description

[stolpeo]

Describe the bug
Brackets are gone for any protein position. As these are predictions they need to be there according to HGVS nomenclature

To Reproduce
Steps to reproduce the behavior:

1. Go to AnyCase
2. Look at any Variant
3. See error eg. p.I2067V

Expected behavior
There needs to be a bracket eg. p.(I2067V)
Carefull "p.?" is written without brackets, e.g. SpliceSiteVariants

Additional context
(https://hgvs-nomenclature.org/stable/background/simple/)](https://hgvs-nomenclature.org/stable/background/simple/#dna-rna-protein)

issue should be fixed in mehari, not in varfish varfish-org/varfish-server#1435

Design considerations

As Varfish performs no hgvs validation, proper formatting and presentation of hgvs strings should be fully handled by mehari.

For different use-cases people might prefer different styles of presentation of hgvs-strings, but default behavior should as faithfully follow official hgvs guidelines as possible.
