fix(docs): tari_template_lib resource builders not showing on rust do…

…cs (#1094)

Description
---
Set to `pub` the visibility of resource builder modules in
`tari_template_lib`

Motivation and Context
---
Currently `FungibleResourceBuilder`, `NonFungibleResourceBuilder` and
`ConfidentialResourceBuilder` don't show up in `tari_template_lib` docs.

This happened because the visibility of the modules containing those
structs was not public, so this PR sets the visibility to public.

How Has This Been Tested?
---
Manually by running `cargo doc --open` on the `tari_template_lib` crate

What process can a PR reviewer use to test or verify this change?
---
See previous section
