List the build tool and every bundle on the skill page

/h5p/skill/ wrote out the full address of each of the skill's files but
none of the files its step 3 fetches where npm cannot be reached, so a
chat with the skill's text alone had to put a bundle's address together
from its type, which a fetch tool may refuse. The page now lists
h5p-author.mjs and every bundle /h5p/bundles/ serves, each at its full
address as its link and its text, named by the author package's
contentTypes, the list writeBundles writes from. The SKILL.md test no
longer expects the type-file address 0.9.0 names, so the pin can move
to the next release without changing it.

Closes #17
