Fix a typo in documentation of bash-exec.

[Kurt-von-Laven]

Follow-up for #1886.

Proposed Changes

1. The corresponding documentation in the auto-generated docs/descriptors/bash_bash_exec.md was updated by mistake in 3d5e615, so it was immediately overwritten. Update the source files
   megalinter/descriptors/bash.megalinter-descriptor.yml and megalinter/descriptors/schemas/megalinter-descriptor.jsonschema.json instead this time.
