fix: skip bash tests on Windows (#19277)

Adds Windows compatibility to toolsdk tests

This PR adds Windows compatibility to the toolsdk tests by:

1. Adding build constraints to exclude bash_test.go from running on
Windows
2. Skipping the WorkspaceSSHExec test on Windows platforms with a clear
message

These changes ensure tests run properly across all supported platforms.
