refactor(lua): rename vim.diff => vim.text.diff #34864

Problem:
`vim.diff()` was introduced before we had the `vim.text` module, where
it obviously belongs.

Solution:
Move it.

---- Optional parameters:
---- @class vim.diff.Opts
---- @inlinedoc
----
---- Invoked for each hunk in the diff. Return a negative number
---- to cancel the callback for any remaining hunks.
---- Arguments:
----   - `start_a` (`integer`): Start line of hunk in {a}.
----   - `count_a` (`integer`): Hunk size in {a}.
----   - `start_b` (`integer`): Start line of hunk in {b}.
----   - `count_b` (`integer`): Hunk size in {b}.
---- @field on_hunk? fun(start_a: integer, count_a: integer, start_b: integer, count_b: integer): integer?
----
---- Form of the returned diff:
----   - `unified`: String in unified format.
----   - `indices`: Array of hunk locations.
---- Note: This option is ignored if `on_hunk` is used.
---- (default: `'unified'`)
---- @field result_type? 'unified'|'indices'
----
---- Run linematch on the resulting hunks from xdiff. When integer, only hunks
---- upto this size in lines are run through linematch.
---- Requires `result_type = indices`, ignored otherwise.
---- @field linematch? boolean|integer
----
---- Diff algorithm to use. Values:
----   - `myers`: the default algorithm
----   - `minimal`: spend extra time to generate the smallest possible diff
----   - `patience`: patience diff algorithm
----   - `histogram`: histogram diff algorithm
---- (default: `'myers'`)
---- @field algorithm? 'myers'|'minimal'|'patience'|'histogram'
---- @field ctxlen? integer Context length
---- @field interhunkctxlen? integer Inter hunk context length
---- @field ignore_whitespace? boolean Ignore whitespace
---- @field ignore_whitespace_change? boolean Ignore whitespace change
---- @field ignore_whitespace_change_at_eol? boolean Ignore whitespace change at end-of-line.
---- @field ignore_cr_at_eol? boolean Ignore carriage return at end-of-line
---- @field ignore_blank_lines? boolean Ignore blank lines
---- @field indent_heuristic? boolean Use the indent heuristic for the internal diff library.
