## Which issue does this PR close?

- Related to apache#25758.

## Rationale for this change

The release README used 50.x examples and had no commands to check,
download or unpack the artifacts in SVN.

## What changes are included in this PR?

In `dev/release/README.md`:

- Use 55.2.0 in the examples.
- Step 2: add the `sed` and `cargo update --workspace` commands for the
version and lockfile.
- Add `svn ls` checks after the uploads, and `svn export` plus `tar xzf`
commands for the release tarball.
- Step 13: keep the last major release (`55.0.0` in the example) and the
releases after it in the `release` SVN, with a short loop that prints
the `svn delete` commands for the other releases.

## What is the testing strategy for this PR?

Docs only. The `sed` commands reproduce the `Cargo.toml` and docs
changes of the 55.2.0 release PR (apache#26037). The loop was run in bash, zsh
and sh against a local SVN repository.

## Are there any user-facing changes?

No.
