fix(mini-indentscope): add animation

[fynnfluegge]

📑 Description

Adds an animation to mini-indentscope with faster border rendering. Personally the slow rendering is very distracting to my eyes. Raising a PR since it feels this distraction is a common perception.

Review Checklist

Does this PR follow the [Contribution Guidelines](development guidelines)? Following is a partial checklist:

Proper conventional commit scoping:

• If you are adding a new plugin, the scope would be the name of the category it is being added into. ex. feat(utility): added noice.nvim plugin

• If you are modifying a pre-existing plugin or pack, the scope would be the name of the plugin folder. ex. fix(noice-nvim): fix LSP handler error

• Pull request title has the appropriate conventional commit type and scope where the scope is the name of the pre-existing directory in the project as described above

• README is properly formatted and uses fenced in links with <url> unless they are inside a [title](url)

• Entry returns a single plugin spec with the new plugin as the only top level spec (not applicable for recipes or packs).

• Proper usage of opts table rather than setting things up with the config function.

• Proper usage of specs table for all specs that are not dependencies of a given plugin (not applicable for recipes or packs).

we normally stick to the default.
u always can overwrite the setting for yourself locally.
i guess it would be unexpected have different defaults

[fynnfluegge]

Alright, thought this would be a better default. Closing it, thanks for the response!

it makes more sense to ask upstream to change the default.. but i guess mini will not change it
