package -> @_spi public due to package exportability rule updates (#7525)

elsh · web-flow · commit 605e22860e04 · 2024-05-03T04:27:59.000-07:00
The exportability rules around `package` access level are updated in a way that an `@_spi public` can't be bound to a `package` var, similar to how `@_spi public` can't be bound to a `public` var. For reference, see swiftlang/swift#73161. This PR corrects such use case.
