Skipped tests always show 0

From comment resolved as out-of-scope in previous PR: https://github.com/Azure/azihsm-sdk/pull/108#discussion_r2790521562. The test summary currently will always report the number of skipped tests as 0 due to a known issue in nextest: https://github.com/nextest-rs/nextest/issues/885. Way I see this currently, there are two possible fixes for this:

1. submit a fix for this in nextest's repo
2. develop a workaround in this repo (possibly by parsing stdout)

Second opinions on preferred fix or suggestions for alternate fixes would be appreciated.

Start by reviewing how this repository obtains and formats the test summary, then read the linked nextest issue and the prior PR discussion. Compare fixing nextest upstream with a repository-local workaround such as parsing stdout. Done means the summary reports the actual number of skipped tests and the relevant test coverage passes.
