Add missing APIs for tags

[bitbonk]

Mastodon has some APIs for tags that are still missing in IMastodonClient:

• view information about a single tag: https://docs.joinmastodon.org/methods/tags/#get
• follow a tag: https://docs.joinmastodon.org/methods/tags/#follow
• unfollow a tag: https://docs.joinmastodon.org/methods/tags/#unfollow
• view followed tags: https://docs.joinmastodon.org/methods/followed_tags/#get

It would be cool, if they would be added.

It's done, you can get the last nuget package (2.0.3), and you will have the new methods :

Task<Tag> GetTagInfo(string tag);
Task<Tag> FollowTag(string tag);
Task<Tag> UnfollowTag(string tag);
Task<MastodonList<Tag>> ViewFollowedTags(ArrayOptions? options = null);
