[PATCH v3] doc: bitbake-user-manual: grammar fix for the number of "metadata"

["Michael Opdenacker" <michael.opdenacker@bootlin.com>]

"metadata" is used both as singular and as plural.
The first change fixes a case in which the verb has a singular conjugation
but absence of article indicates a plural case.

The second and third changes are for consistency with the first one inside
the same paragraph.
