fix(themes): add the shell command token to the theme template and docs

#3458 added --syn-shell-command without setting it in the Harbor Night
scheme (the template new themes start from) or regenerating plugins/themes.md,
so scripts/theme/theme.test.ts failed. Imported IntelliJ schemes map
BASH.EXTERNAL_COMMAND to it.
