Bad custom textobjects snippet example for select keymaps in the README

[den-is]

Here:

go.nvim/README.md

Lines 986 to 992 in 3ea80d7

	["iF"] = {
	python = "(function_definition) @function",
	cpp = "(function_definition) @function",
	c = "(function_definition) @function",
	java = "(method_declaration) @function",
	go = "(method_declaration) @function"
	}

Example shows outdated configuration snippet for select keymaps.
This is not allowed anymore, you can't set per language custom textobjects like this.

Exact issue describing old snippet in the README: nvim-treesitter/nvim-treesitter-textobjects#65

Doc: https://github.com/nvim-treesitter/nvim-treesitter-textobjects?tab=readme-ov-file#overriding-or-extending-textobjects

Personally, I did not know anything about textobjects and stuff, just wanted to follow go.nvim guide and add a little bit of fancy-schmancy features. Occurred that I broke my nvim setup, and had to learn new ... stuff. :)
