docs: Update transparent sessions interoperability matrix (#1445)

Per [ICU-18237](https://hashicorp.atlassian.net/browse/ICU-18237), the
transparent sessions interoperability matrix should be updated with the
3rd party test results for version 0.20.1.

This PR adds updated 0.20.1 test results for CloudFlare WARP, Huntess,
SentinelOne Singularity, and Zscaler ZPA. It also removes test results
for the older 0.1.4 and 0.19.5 versions,
