Rollup merge of #138335 - jieyouxu:fix-citool, r=marcoieni

Fix post-merge workflow

The command is called `post-merge-report` not `post-merge-analysis`. See https://github.com/rust-lang/rust/blob/90384941aae4ea38de00e4702b50757e9b882a19/src/ci/citool/src/main.rs#L379

Noticed it failing in rust-lang/rust#138310 (comment).

r? ``@Kobzol`` (or ``@marcoieni)``
