MDL-79181 core: update LinkedIn OAuth template to use OIDC
The old method (sign in with linkedin) is deprecated:
https://learn.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/sign-in-with-linkedin

This replaces this with the new method:
https://learn.microsoft.com/en-us/linkedin/consumer/integrations/self-serve/sign-in-with-linkedin-v2

This is not entirely OIDC compliant, however. The well known
openid-configuration isn't present at the issuer root and the 'locale'
claim contains an object instead of a string. These are worked around.

/**
* Class linkedin.
*
* OAuth 2 issuer for linkedin which is mostly OIDC compliant, with a few notable exceptions which require working around:
*
* 1. LinkedIn don't provide their OIDC discovery doc at {ISSUER}/.well-known/openid-configuration as the spec requires.
* i.e. https://www.linkedin.com/.well-known/openid-configuration isn't present.
* Instead, they make the configuration available at https://www.linkedin.com/oauth/.well-known/openid-configuration.
* See: https://openid.net/specs/openid-connect-discovery-1_0.html#ProviderConfig
*
* 2. LinkedIn don't return 'locale' as a string in the userinfo but instead return an object with 'language' and 'country' props.
* See: https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims
* This is resolved in {@see \core\oauth2\client\linkedin::get_userinfo()}
