Fix bufferline cycle

[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.
