feature request: Support issuing Access Token JWTs with typ other than at+jwt (e.g. JWT)

[ChrisSamo632]

What problem did you meet?

LogTo Access Token JWTs are always issued with a typ of at+jwt, but not all services are able to consume these tokens, for example Elasticsearch (elastic/elasticsearch#119370) or any Spring-based application using the default JWT Decoder (as noted in the LogTo docs - https://github.com/logto-io/logto/blob/master/packages/console/src/assets/docs/guides/api-spring-boot/README.mdx).

For example, when requesting by an Access Token JWT machine-to-machine Application for an API Resource and permitted scopes - the JWT is returned without issue by LogTo, but then cannot be consumed by the target application.

Describe what you'd like Logto to have

An option to return Access Token JWTs with typ of JWT for use in a wider number of target applications
