games/anki: Update to 2.1.54

• Remove BROKEN for aarch64 as the FreeBSD related sections in the Bazel rules should now be architecture independent.

• Build a separate binary version of "esbuild" beforehand as the JS counterpart, which is used by the Bazel NodeJS ruleset, has fixed version checks that cannot patched out easily.
