FIX: Update gRPC API version check and improve exception handling

[Samuelopez-ansys]

Description

This pull request updates the logic and documentation around enabling the gRPC API for the EDB module, making it available only for AEDT version 2026 R2 and later (previously 2026 R1). It also introduces improved exception handling and ensures consistent behavior regarding resource release on exceptions, particularly in console and Jupyter environments.

gRPC API Version Requirement Updates:

• Updated documentation in pyaedt_settings.yaml and settings.rst to specify that the gRPC API for EDB is enabled by default only for AEDT version 2026 R2 or later, instead of 2026 R1.

• Changed version checks in edb.py so that gRPC is enabled only if AEDT version is greater than 2026.1, aligning code behavior with the new documentation.

Exception Handling and Resource Management:

• Modified raise_exception_or_return_false in general_methods.py to always use the close_on_exit attribute when releasing or closing desktops, improving reliability and consistency in cleanup logic.
• Set settings.release_on_exception = False in both console_setup.py and the Jupyter notebook template to ensure that exceptions in these environments do not trigger resource release, preventing unintended closures.
