Bug 19833: (follow-up) Minor corrections

This patch makes minor corrections to lines modified in the previous
ones.

On the biblio framework page, I have deleted this line because it didn't
make much sense before or after the change:

"Framework name, then go to MARC biblio to set MARC editor parameters"

In the web services preferences file, I reverted a change to
"deletedbiblio" because it refers to a table name.

I've also made corrections to instances of "biblio" in the following
pages, including changing "biblio number" to "biblionumber," since it
refers to a specific Koha column name.

- MARC detail page
- Help files:
  - Record matching rule;s
  - Batch item modification
  - MARC modification templates
- Export data
- Staged MARC record management
