doc: fix directory definition in nix-archive.md (#10997)
* doc: fix `directory` definition in nix-archive.md

Before the change the document implied that directory of a single entry
contained entry:

    "type" "directory" "type" directory" "entry" ...

After the change document should expand into:

   "type" "directory" "entry" ...

1c75af969a Document store object content addressing & improve JSON format
The JSON format no longer uses the legacy ATerm `r:` prefixing nonsese,
but separate fields.

Progress on #9866

043135a848 Document file system object content addressing
In addition:

- Take the opportunity to add a bunch more missing hyperlinks, too.

- Remove some glossary entries that are now subsumed by dedicated pages.
  We used to not be able to do this without breaking link fragments, but
  now we can, so pick up where we left off.

a34ec0bd12 Include store path exact spec in the docs
This is niche, but deserves to be in the manual because it is describing
behavior visible to the outside world, not mere implementation details.

7ad66cb3ef Allow dynamic derivation deps in inputDrvs
We use the same nested map representation we used for goals, again in
order to save space. We might someday want to combine with `inputDrvs`,
by doing `V = bool` instead of `V = std::set<OutputName>`, but we are
not doing that yet for sake of a smaller diff.

The ATerm format for Derivations also needs to be extended, in addition
to the in-memory format. To accomodate this, we added a new basic
versioning scheme, so old versions of Nix will get nice errors. (And
going forward, if the ATerm format changes again the errors will be even
better.)

`parsedStrings`, an internal function used as part of parsing
derivations in A-Term format, used to consume the final `]` but expect
the initial `[` to already be consumed. This made for what looked like
unbalanced brackets at callsites, which was confusing. Now it consumes
both which is hopefully less confusing.

As part of testing, we also created a unit test for the A-Term format for
regular non-experimental derivations too.

880d9cabed Test and begin documentation of the ATerm format for derivations
Wanted to do this before the last dynamic derivations PR when I
introduce a variation, to make sure I wasn't changing the old version by
mistake.
