fix(bufferline-nvim): add bufferline cycle bindings

[acarl005]

Map [b and ]b to the bufferline-specific calls for cycling buffers.

📑 Description

I included astrocommunity.bars-and-lines.bufferline-nvim and observed the ]b and [b bindings not behaving correctly. They were switching buffers, but out-of-order w.r.t. how they were displayed in bufferline. This PR remaps those to call bufferline's specific API for cycling through tabs. With this custom binding added, I now observe the correct behavior.

ℹ Additional Information

It's not super straightforward to repro. Sometimes, I open a project, open various buffers, and press ]b and the ordering is correct. Other times, after opening some buffers, say with gd or from telescope searches, the buffer navigation starts happening out of order.

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)

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

You should add a readme note about the keybinding since you're overriding the default
