Update on "[docs] Add "See Also" blocks for torch.t and `torch.tran…

…spose`"


**Summary**
PR 63177 added "see also" cross-references to `torch.t` and
`torch.transpose`. However, it did so in the form of simple links
preceded by the phrase "See also". A comment on the aforementioned PR
pointed out the RST has special syntax to render a "See Also" box that
is more noticeable. This commit converts the "see also" sentences for
`torch.t` and `torch.transpose` to boxes.

**Test Plan**
Continuous integration.
