passed custom template in BuildApp()

[DJSanti]

What was changed

A custom help template was massed in the arguments for BuildApp().

Why?

The template prevents text meant for documentation (text with markdown) from being displayed in the CLI tool itself.

Checklist

• Pass variable
• Compile and confirm that it works

How was this tested:

Compiled app and ran commands and -h.

Any docs updates needed?

Documents will be updated upon next generation.

Nice, we still have some work here but I'm no longer seeing markdown rendered.

I'm seeing [arguments...] show up in commands that don't support them, e.g:

   temporal task-queue describe [command options] [arguments...]

And very long lines that are hard to read and should be broken up, e.g:

   The Server records the last time of each poll request. Poll requests can last up to a minute, so a LastAccessTime under a minute is normal. If it's over a minute, then likely either the Worker is at capacity (all Workflow and Activity slots are full) or it has shut down. Once it has been 5 minutes since the last poll request, the Worker is removed from the list.

Hmm... nope still seeing markdown rendered:

$ temporal workflow --help
NAME:
   temporal workflow - Operations that can be performed on Workflows.

USAGE:
   Workflow commands allow operations to be performed on [Workflow Executions](/concepts/what-is-a-workflow-execution).

Please review all of the help outputs and verify we don't render markdown.
We should consider having a single help text in markdown form and rendering it as text when printed to console.

declared the template explicitly for main commands.

edited the condition for printing [arguments...].

Might close this PR if Ruslan has a better idea
