In f6d25d7878 (api docs: document that BUG() emits a trace2 error event,
2021-04-13), a link to the plain text version of api-trace2 was added in
`technical/api-error-handling.txt`.

All of our other `link:`s point to the html versions.  Do the same here.

This is minor, but I noticed it while working on the previous patch.  The
effect can be see at [1] where we link to [2].

Somewhat related, it also appears that the link to the API docs in the "Further
documentation" section on git-scm.com is broken entirely[3].  I didn't try to
chase down why that might be, but perhaps someone who knows the site build
process can fix it up.
