Fix: Missing update hook for lgms_modules_disabled field on existing installs

[sinhaparth5]

Description

The field lgms_modules_disabled was introduced to the localgov_microsites_group module (found in config/install), but there is no corresponding update hook to create this field for sites that were installed prior to its introduction.

Currently, code in ContentTypeHelper::moduleEnable() assumes this field exists. On older installations, this leads to fatal errors or warnings because the Entity API cannot find the field definition in the active configuration, even if the column has been manually added to the database.

Proposed Resolution
Add an update hook (10002) to localgov_microsites_group.install that:

Checks if field.storage.group.lgms_modules_disabled exists.

Checks if field.field.group.microsite.lgms_modules_disabled exists.

Creates them programmatically if they are missing to bring the site schema in line with the module's config/install definitions.
