Imported types cannot be used as array keys in 5.18.0

[TJ09]

<?php

/**
 * @psalm-type ArrayKeyType array-key
 */
class Bar {}

/**
 * @psalm-import-type ArrayKeyType from Bar
 * @psalm-type UsesArrayKeyType array<ArrayKeyType, bool>
 */
class Foo {}

Note that there are no errors in psalm.dev at the time of writing (but it's also running a week-old commit: a75d26a).

Psalm 5.17 reports no errors, while Psalm 5.18 reports:

ERROR: InvalidDocblock - lib/Foo.php:12:1 - Invalid array key type ArrayKeyType (see https://psalm.dev/008)
/**
 * @psalm-import-type ArrayKeyType from Bar
 * @psalm-type UsesArrayKeyType array<ArrayKeyType, bool>
 */
class Foo {}

As far as I can tell ArrayKeyType as array-key is definitely an okay array key type.

I found these snippets:

https://psalm.dev/r/72f05104ae

<?php

/**
 * @psalm-type ArrayKeyType array-key
 */
class Bar {}

/**
 * @psalm-import-type ArrayKeyType from Bar
 * @psalm-type UsesArrayKeyType array<ArrayKeyType, bool>
 */
class Foo {}

Psalm output (using commit a75d26a):

No issues!

Yeah, I expected this, since I don't have a complete list of all string-ish types of psalm. This is a good first issue to add the additional types to the conditions there - validate that they are any of the allowed array-key types though
