[DOCS] Switch to correct code-block languages

While Sphinx ignores case of code-block
languages the new code-highlighter is
code-sensitive. So converting the cases
all to lowercase.

There is no language called mysql in
the new highlighter. In Sphinx this
was an alias for sql. It does not
really make sense to use mysql here,
as the examples would also work in
Maria-DB.

A backport is no necessary as
there were no content changes and we
only render the main branch for
the changelog
