Subject: [PATCH] fix: use f-string with separator in switch operator error
 message (#13915)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

\`switch.py\` line 137 concatenates the operator directly after the text
without separator:
\`'Not supported operator' + operator\` → produces \`"Not supported
operatorXXX"\`

Changed to: \`f'Not supported operator: {operator}'\`
