Provide flag to only display tsh binary version

[stevenGravy]

Implements #17817

Before

$ tsh version
Failed to fetch proxy version: no profile provided and no current profile
Teleport v13.0.0-dev git: go1.19.5

Now can do

$ tsh version --client
Teleport v13.0.0-dev git: go1.19.5

Alternatively, we could drop the new flag and only report the proxy version if able to connect to it.

But then you'd still get an error if the proxy is unreachable.

That's what this gh issue ask was. #17817

I was suggesting that we could treat errors connecting to the proxy or retrieving the version indicate that tsh version should omit the proxy version from the output instead of causing the command to exit with an error. If we did that then the new flag wouldn't be necessary.

Realizing that this is a new feature and the documentation for it, we should probably separate the docs into a different PR that can be backported separately after the feature is released into each major version.

Docs adjustments should be separated so that they don't go live before the feature changes are released.

They have been removed and will be put in a sep PR
