Remove ZeroTrust deployment type

[mssalvatore]

Having a ztwindows, ztdocker, etc. deployment type adds time and complexity to the build process without providing a lot of value. Remove these deployment types and simplify the build process.

• [x] Investigate and repair outdated documentation in Confluence (0d)

The analytics lambda only references the ZT deployments in a lookup table. When requests come in, it looks up the reported deployment type in the table. Removing the ZT deployments from the table would result in incomplete data for older versions of Infection Monkey.

TLDR; No changes are required for the lambda.
