build: skip dockit on riscv64

[sxa]

The doc-only target gives a variety of failures on different riscv64 systems. These symptoms are described in nodejs/build#4099 (comment) in the section Additional info on the Wasm doc-only crash

This removes the doc-only target from being run by default as part of make test-ci similar to what has been done for AIX and IBMi.

I think we can fix it (at least the WebAssembly.instantiate(): Out of memory: Cannot allocate Wasm memory for new instance part) by bumping @nodejs/doc-kit after nodejs/doc-kit#691 is merged.

Probably fixed with the updae in #62512 - running a test on my K1 at https://ci.nodejs.org/job/sxa-rvnodetest/399/

Noting that I hit this again today with a branch that had the doc-kit 1.4.1 added in https://github.com/nodejs/node/pull/64010/changes so this may still be required.
