docs: Fix subject identifier algorithms to match configuration

[LemurP]

On https://www.ory.sh/hydra/docs/reference/configuration/ under 'subject identifiers' the name for defining which subject identifier algorithms are supported it is called "supported_types", not "enabled" as in these pages.

Testing shows that "supported_types" is the correct value for use in Hydra.

Further comments

The page I have made a change to created some confusion when we enabled pairwise subject identifiers.
I don't care to read all the policies, as it is a miniscule change. Sorry.

Thank you very much for your contribution to the documentation! Due to the way Docusaurus versioning works, you need to make the changes in two locations:

• docs/versioned_docs/version-v{version}/path/to/file
• docs/docs/path/to/file

Without making them in both locations, the changes will most likely be lost when releasing another version. Thank you! :)

[LemurP]

I've made the same change in the docs/docs/path/to/file now.

Hope that's all that is needed. :)
