fix(auth): pass GOTRUE_JWT_VALID_METHODS env var for GoTrue compat

[cemalkilic]

the envvar name is updated to be consistent with the rest. (supabase/auth#2334)
for now keeping the deprecated GOTRUE_JWT_VALIDMETHODS for backward compatibility, we can remove it in near future.

Summary by CodeRabbit

• Chores
  • Added support for new JWT environment variable name (GOTRUE_JWT_VALID_METHODS) for configuring allowed JWT signing methods.

Walkthrough

This change adds a new environment variable GOTRUE_JWT_VALID_METHODS to the configuration system alongside the existing GOTRUE_JWT_VALIDMETHODS. Both variables accept the same JWT signing methods (HS256, RS256, ES256). An inline comment was added indicating the old VALIDMETHODS variable should be removed after a transition period.
