fix: close drill capture template source link

The "d" drill capture template had a malformed source link with only one closing bracket and a literal `n` where a newline should have been:

    Source: [[%:link][%:description]
    nCaptured On: %U

So new drill captures wrote a broken link and `nCaptured On:` instead of a clean `Captured On:` line on the next row.

I closed the link with the missing `]`, and removed the stray `n` so the line break before "Captured On" is just a real newline. The "f" (PDF drill) template was already correct, so I left it alone.

I added `tests/test-org-capture-config-drill-template.el`. It loads the module, picks up the "d" template, and asserts both the closed link and the `\nCaptured On: %U` form, plus negative assertions against the broken pre-fix shapes.
