Add consoleTitle to launch.json properties schema (#22406)

consoleTitle is effectively an undocumented feature. pydebug accepts the
config key, but vscode will report a problem because it is missing from
the schema. see [this debugpy
issue](microsoft/debugpy#1178) and
[#13040](#13040)

I used the phrase "console or terminal" because I noticed the name was
represented on both integratedTerminal and internalConsole. I didn't
test externalTerminal.
