Switch OCA references of credential_support_url to issuer_url

[knguyenBC]

Background

When a proof request is received and the user does not have the credential, the wallet uses credential_support_url from OCA as the hyperlink for the "Get this credential" button. This is counter intuitive as that credential_support_url is meant to be the hyperlink to the support url (i.e. the contact us page or email) for the credential. It is meant to be accompanied by the credential_help_text (and it's text display). This is defined in the credential design guide: https://bcgov.github.io/digital-trust-toolkit/docs/resources/guides/credential-ux-guide#credential-meta-information

This is causing some confusion with people building their own OCA bundle.

Acceptance Criteria

Switch the reference from credential_support_url to issuer_url

[knguyenBC]

• LCRB seem to have built their OCA to match how BC Wallet is currently referencing credential_support_url. i.e. their credential_support_url overlay links to the issuance page. However, that link also has a reference to their contact us information so works both ways. Same with their issuer_url.
• The student card OCA is built to match the credential design guide.
• Person credential also uses the same URL for both metadata
• LSBC has their credentials to use the same URL for both metadata.
• Transcriber credential doesn't have the metadata populated
• LTSA also uses the same URL for both metadata
• Business card doesn't have the metadata populated
• Mines don't have the metadata populated

Conclusion

• a possible minor impacts for LCRB but everything else is fine.
