Editorial: Fix links/phrasing in non-normative text about queries

Copy/pasta and repeated edits had muddled the non-normative text
around various methods explaining the query parameter, namely "The
query parameter... identifying the record/records/values/keys..." was
inconsistent in phrasing. plurals and link targets. This cleans it up,
resulting in:

IDBObjectStore.delete()     - [object-store] records
IDBObjectStore.get()        - [object-store] record value
IDBObjectStore.getKey()     - [object-store] record key
IDBObjectStore.getAll()     - [object-store] record values
IDBObjectStore.getAllKeys() - [object-store] record keys
IDBObjectStore.count()      - [object-store] records

IDBIndex.get()              - [index] referenced value
IDBIndex.getKey()           - [object-store] record key
IDBIndex.getAll()           - [index] referenced values
IDBIndex.getAllKeys()       - [object-store] record keys
IDBIndex.count()            - [index] records

... where [blah] above is disambiguating the link target just in this
commit comment, not in the actual text.

As a reminder, an index record's *value* is a *key* in the referenced
object store; since this is downright confusing and we're just talking
about informative text, the link above is to an object store's record
key.
