I am not sure about the side-effect of this. IMO it will be better if
"Username Template Importer" mapper is allowed as the mapper in the
github provider (as well as other social providers). Then it will work
with the Github provider without need to configure Github as generic
OIDC. If you are able to create JIRA and send PR for this change, it
will be nice :)

According to the GitHub docs , the token URL returns its content in
a different format depending on the HTTP header received. Keycloak
seems to parse it as JSON, so it could make sense to include the
header "Accept: application/json" in the request. Would this change
fix the parsing error?
