fix: Remove duplicate `LazyLock` example.

The top-level docs for `LazyLock` included two lines of code, each
with an accompanying comment, that were identical and with nearly-
identical comments. This looks like an oversight from a past edit
which was perhaps trying to rewrite an existing example but ended
up duplicating rather than replacing, though I haven't gone back
through the Git history to check.

This commit removes what I personally think is the less-clear of
the two examples.
