repo.json

[taconi]

Add repos.json file for installation via micro -plugin install.
The documentation talks about this in more detail.

I know about that. The reason I haven't added repo.json is that this plugin largely depends on the still-not-merged PR micro-editor/micro#2605. (So I can't specify the minimum supported version of micro in repo.json, since there is no such version.)

Well, I'm actually considering implementing possibility to use this plugin with keyboard only, without using mouse. Then it will be at partially useful without micro-editor/micro#2605.
