COBOL Folding - Remove or limit dependency on COBOL Language Server (do not disable folding in case of program error)

[FALLAI-Denis]

Description of the enhancement requested

In relation to issue:

• COBOL - Folding on Division, Section, Parapraph #94

COBOL folding is now natively supported in ZOE.
Thanks for that. 🤩

However, this functionality is linked to the processing provided by the COBOL Language Server, and any program error detected during these processes disables folding... (a copybook not found disables the folding function...).
However, folding can be very useful even in the processing of coding errors in a program. The folding function should be maintained even in the event of an error in the program.

Thanks.
