Unclear if alg_values_supported under vp_formats_supported is mandatory for all vp formats

[Oliver Terbu]

Unclear if alg_values_supported under vp_formats_supported is mandatory for all vp formats. I’d suggest to make it optional and let it depend on whether the format requires it. for some formats, it is not straight forward what alg values should be. sometimes, especially for static wallet metadata, it might not be 100% clear to define alg_values_supported either.
