[documentation]mcrun support the -t option?

[stc1988]

I found that mcrun supports -t build option since Moddable SDK 4.3.4.
On the other hand, the documentation still states that it is not supported.

You raise a good point.

The reality is a little complicated.. -t build is supported but other options for -t such as clean are not supported for all target platforms (and deploy doesn't appear to be supported for any target).

I'll update the documentation to mention that -t build is supported.

I confirmed this fixed.
