Pheweb risteys link is handled differently in the index page and phenotype page

[Lipastomies]

Phenotype page should function like index page.
Relevant parts:
Phenotype model: https://github.com/FINNGEN/pheweb/blob/master/ui/src/common/commonModel.tsx#L206-L218
Risteys link overriding (current): https://github.com/FINNGEN/pheweb/blob/master/ui/src/components/Phenotype/phenotypeAPI.tsx#L52-L63
Preferred behaviour regarding risteys link: https://github.com/FINNGEN/pheweb/blob/master/ui/src/common/commonTableColumn.tsx#L174-L182

The risteys link itself is configured in config.js as part of a banner.
