What kind of change does this PR introduce?

• Feature
• Bug Fix
• Refactoring (no functional or API changes)
• Documentation Update
• Maintenance (dependency updates, CI, etc.)

Summary

Added the possibility to define the description of a custom command as an array of strings, to improve the readability of long comprehensive descriptions in json format. Each string will result in a single line of searchbnf.conf or within the description of the command python.

Changes

Modification of the json schema to allow a string array as description and modified the searchbnf.conf generator and the custom command python generator to format the description accordingly.

This is another update after #1977, #1979 and #1980.

User experience

It is now possible to split long descriptions in multiple lines, which improves the readability in globalConfig.json.
