[stable-2.9] validate_modules: fails with .id attribute not found (#73322) (#74179)

* validate_modules: fails with .id attribute not found

This patch addresses a problem in the `found_try_except_import` test.

This module tries to identify lines like:

`HAS_FOO = True`

In this case, the target (`HAS_FOO`) is of type `ast.Name` and has a
`id` attribute which provide the name.

In my case, I've a line that set a module attribute`. In this case, the
target (`module.var`) has the type `ast.Attribute` and no `id`
attribute. The code trigger an `AttributeError` exception.

This patch ensures we compare a `ast.Name`.

* Update test/lib/ansible_test/_data/sanity/validate-modules/validate_modules/main.py
