Updated Account to latest fields, supporting more account preferences, updated Post edit to include languge

[technicat]

Added noindex, indexable, hideCollections, and role to Account, which supports opting in/out of search and hiding follower/followee info from the public, and updated/added TootSource and TootRole accordingly (see added test cases for reference)

Also fixed missing snake case mapping in PostEditParams which was losing spoilers and attachments.

@technicat That's quite the change! Thank you so much 🙌

✅ indexable, noindex and hideCollections looks good.

✅ EditPostParams looks good.

✅ TootSource looks good.

✅ UpdateCredentialsParams looks good.

✅ 🎉 Unit Tests ❤️

Regarding the role field, I think we need a little bit more to support it. Can we take it out of this PR?

Some thoughts: Pleroma uses "roles" as an object with a boolean field for "admin" or "moderator" which we can handle during serialization. I like the TootRole concept, perhaps we could simplify this object a bit to allow us to fill-in values when coming from other flavours (e.g. remove the id field, and change color, permissions and highlighted to Optional) Also, Mastodon only returns a role for "CredentialAccount", not regular "Account" so we should consider creating a dedicated model for the endpoints which actually return a role field.

@technicat On second thought, I'm OK to merge this if we can simplify TootRole so tweaking the serialization for pleroma will not cause too much breakage.

@technicat On second, second thought 😅, it seems supporting the Admin API calls for Pleroma/Akkoma's roles will be very much a dedicated effort as they require an entirely specific set of endpoints and models. Let's go with the Mastodon's role for now.
