[FEATURE] | Check if Users using 'chr21' or '21' notation in input VCFs

[G-kodes]

Is your feature request related to a problem? Please describe.
Currently, the pipeline does not check if a user is using vcf input with 'chr21' or '21' notation. Plink-2 does explicitly require 'chr21' notation to function so this really should be checked beforehand and converted if needed.

Describe the solution you'd like
Inclusion of additional python scripts in the VALIDATE rule to check notation type and if required, convert it (AWK or SED?).

Describe alternatives you've considered, if any
Not checking and just letting it break? Not gonna lie, not a great alternative...

Rust might be an ideal, lightweight option for this. It already has promising libraries for VCF parsing
