change improves the flexibility of the limactl shell command when used with the 
--preserve-env flag by validating environment variable patterns to only 
allow alphanumeric characters and underscores also allowing 
more flexible environment variable filtering.

Fixes
#4036

I haven't actually run the code, but from reading the changes, it doesn't look like it implements the modified allow list semantics.

It is also missing tests for the changes.

I think the tests need another round of simplification.

I think the tests could still be tightened up, but the actual functionality seems to be working as expected.

So I'm going to merge; tests can always be refactored some more later.

I don't think having a second unrelated variable proves anything, but it doesn't hurt.

I think this test case is mostly redundant with the allow list can use a , separated list with whitespace ignored one, except it also tests the "append" functionality. So these tests could be combined.
