Fix failing tests, running tests on Mac (#87)

suite3 was failing because it relied on what the server wrote to
.smithy.lsp.log, which has to be enabled through the setting
'smithyLsp.logToFile'.

suite4 test workspace had updated smithy trait package dependency
versions, but the assertions weren't updated to match. Side note:
I think its fine to keep these tests at smithy 1.40, since the
extension/server should work fine with whatever smithy version.
Also needed the same setting as suite3.

Also had to update a dependency so tests could successfully run on
Mac.
