ci: Runner now uses Swift 6.2; update the Static SDK to match (#159)

Motivation
----------

End to end and integration tests are failing because the underlying
Swift CI runner has been updated to use Swift 6.2 but these tests
install the 6.1 release of the Static Linux SDK.

Modifications
-------------

Update end to end and integration workflows to install the the 6.2
release of the Static Linux SDK.

Result
------

All tests will pass again.

Test Plan
---------

All existing tests pass again.
