Add container name to lsp symbol entry

[benjiwolff]

Description

worspace/symbol returns context information (containerName) for each symbol (see spec).
However, neovims symbols_to_items ignores containerName, so we add it manually to the picker entry.

This is the smallest change required to use the existing lsp_dynamic_workspace_symbols picker and friends with a custom entry_maker, that includes containerName.

I am new to this codebase and don't know the reason behind using symbols_to_items. It returns vim.quickfix.entry[] which seems inappropriate for workspace/symbols. Maybe, it could be dropped altogether.

Fixes #2695

Type of change

• New feature (non-breaking change which adds functionality)
• This change requires a documentation update ❓

How Has This Been Tested?

I used the following custom entry_maker with seblyng/roslyn.nvim.

custom entry_maker

M.workspace_symbols = function() telescope_builtin.lsp_dynamic_workspace_symbols({ entry_maker = workspace_symbols_entry_maker, }) end

local lsp_type_highlight;
workspace_symbols_entry_maker = function(entry)
local symbol_type, symbol_name = entry.text:match("%[(.+)%]%s+(.*)")

local displayer = entry_display.create({
	separator = " | ",
	items = {
		{ width = 8 },
		{ width = 10 },
		{ remaining = true },
	},
})

local make_display = function()
	return displayer({
		{ symbol_type:lower(), lsp_type_highlight[symbol_type] },
		symbol_name,
		entry.container_name,
	})
end

return {
	value = entry,
	ordinal = symbol_type,
	display = make_display,
	lnum = entry.lnum,
	col = entry.col,
	filename = entry.filename,
}

end

lsp_type_highlight = {
["Class"] = "TelescopeResultsClass",
["Constant"] = "TelescopeResultsConstant",
["Field"] = "TelescopeResultsField",
["Function"] = "TelescopeResultsFunction",
["Method"] = "TelescopeResultsMethod",
["Property"] = "TelescopeResultsOperator",
["Struct"] = "TelescopeResultsStruct",
["Variable"] = "TelescopeResultsVariable",
}
