[feat] Support modes other than insert for input_buffer_type = "dressing" about inc-rename.nvim

[smjonas]

Unfortunately, adding support for insert_only is currently not possible to implement. Support for dressing.nvim is implemented as follows:

• the dressing window is opened with a "fake cursor" (i.e. I just put a highlight in the dressing buffer)
• the real cursor still stays in the command line because the preview of the LSP renaming must take place from command line mode due to the way cmd-preview works in Neovim

So a setting like insert_only does not make sense because you are not actually moving around in the dressing window. You can, however, override settings globally using dressing's setup function as shown in the readme. I hope that clears things up!
