📝 Fix list-table indentation in comment-style table

The JSONC row added the continuation cells one space too deep and
re-indented the existing Go row the same way, so both rows' cells sat
at column 6 under a `* -` whose first cell is at column 5. docutils no
longer saw a uniform two-level bullet list, failing the directive:

  configuration.rst: ERROR: Error parsing content block for the
  "list-table" directive: two-level bullet list expected, but row 7
  does not contain a second-level bullet list.

Under `sphinx-build -nW` (the `docs` CI job) this broke the build.
Dedent both rows' cells to column 5, matching every other row.
