Read-Only attributes -- Display LN description in the IED plug-in

[DavoodSooran]

Describe the bug

For more information about this bug, refer to: #1465

Currently, in the Edit LN and Edit LN0 wizards, most of the attributes are editable. It is important to note that these attributes are part of the reference to the logical node and editing them could break some elements in the SCL file. Therefore, as a user, I should only be able to edit the LN Description.

Describe the solution you'd like
Upon selecting the Edit icon for LLN0 or any other LNs, users will be presented with the Edit LN0 or Edit LN wizard interfaces. To prevent users from inadvertently breaking elements in the SCL file by changing the attributes, all attributes in these wizards will be disabled except for the LN Description, which will remain editable.

It is important to note that in the Edit LN wizard interface, the toggle button for the prefix attribute should be removed. This will ensure that all attributes are read-only, except for the LN Description, which will be editable. More information on how the LN Description should work can be found below.

The 'desc' attribute, classified as optional according to the IEC standard, has been implemented as a toggle button. This design allows users the flexibility to enable or disable the 'desc' attribute as needed. When the 'desc' attribute is enabled within the wizard, it will be incorporated into the generated SCL file, as demonstrated in the illustration below. Furthermore, the 'desc' attribute will be visibly displayed alongside the Logical Node name in the IED browser.
