Description

Hi, and thank you for this incredible project, it is slowly conquering my config :)

I think it would be cool if modules that deal with movements were able to make them repeatable with , and ;. Some examples of this behaviour would be:

• with mini.bracketed, pressing ]i takes you to the next indent, and pressing ; afterwards takes you to the next one again. Pressing , would instead bring you to the previous one. Same could be done with the movements that are local to the buffer, such as treesitter nodes, diagnostics, comment blocks etc.
• with mini.ai, pressing g[' takes you to the first quote in a pair, pressing ; afterwards does it again. This is also implented in nvim-treesitter/nvim-treesitter-textobjects
• with mini.jump, this is already working with the ; key. It would be a matter of integrating it with the general mechanism used for the other modules.

There is an implementation of this in https://github.com/nvim-treesitter/nvim-treesitter-textobjects/blob/master/lua/nvim-treesitter/textobjects/repeatable_move.lua
It is written so that other plugins can hook into it, making their respective moves repeatable, but I feel like such a mechanism would be better suited to a project like this, as it is more general in scope and it already has many modules it can be hooked into.

Start by reading the referenced nvim-treesitter/textobjects repeatable_move.lua implementation, then inspect the movement behavior described for mini.jump, mini.ai, and mini.bracketed. Done means the modules can use a shared mechanism to repeat their movements with ; and reverse them with ,, including the examples in the issue.
