Fixes the formatting (#45308)

Before
====

```
2024-07-04 15:54:39,084 INFO metabase.server :: Shutting Down Embedded Jetty Webserver

```

And now it will correctly log

```
2024-07-09 16:04:28,345 INFO db.liquibase :: Waiting for migration lock(s) to be released (max 0.4 secs)
```

Why no tests?
====

There _is_ a test that would have caught this. And in fact running at
the repl will catch it:

```clojure
liquibase=> (do (require 'clojure.test 'metabase.db.liquibase-test)
                (clojure.test/run-test metabase.db.liquibase-test/wait-for-all-locks-test))

Testing metabase.db.liquibase-test

ERROR in (wait-for-all-locks-test) (Formatter.java:4515)

:h2
 Will timeout if a lock is not released
expected: (= :timed-out (liquibase/wait-for-all-locks sleep-ms timeout-ms))
  actual: java.util.IllegalFormatConversionException: f != clojure.lang.Ratio
```

But this _passes_ in CI:

```
❯ clj -X:dev:test :only metabase.db.liquibase-test/wait-for-all-locks-test
Finding tests took 23.5 s.
Running 1 tests
Running before-run hooks...

Ran 1 tests in 1.461 seconds
3 assertions, 0 failures, 0 errors.
{:test 1, :pass 3, :fail 0, :error 0, :type :summary, :duration 1461.175042, :single-threaded 1}
Ran 0 tests in parallel, 1 single-threaded.
Finding and running tests took 25.0 s.
All tests passed.
Running after-run hooks...
```

And that's because the log level in testing is FATAL and this is an INFO
level log.

Discussed ways to improve this like adding a null logger during CI but
we aren't ready to increase CI times for that just yet.
