docs: make it clear ui. refers to a toml section

There was a question on Discord about why using Difftastic wasn't working as the
diff tool. The root cause was putting `ui.diff.tool` in the wrong toml section,
when the `ui.` component actually refers to the `[ui]` section itself.

This reads kind of weirdly too because _immediately_ after this, the alternative
option of using the `merge-tools` section is suggested; except it uses `[merge-
tools.<name>]` which makes it immediately clear it's a section on its own.

This simply these two examples more consistent with each other, by using `[ui]`
instead of `ui.` to make it clear `ui.` is a top-level section.

@ -172,10 +172,11 @@ If `ui.diff.tool` is set, the specified diff command will be called instead of
the internal diff function.
```toml
[ui]
# Use Difftastic by default
ui.diff.tool = ["difft", "--color=always", "$left", "$right"]
diff.tool = ["difft", "--color=always", "$left", "$right"]
# Use tool named "<name>" (see below)
ui.diff.tool = "<name>"
diff.tool = "<name>"
```
The external diff tool can also be enabled by `diff --tool <name>` argument.
