Fix invalid option names in Firestore backup schedule commands

[TomasMorton]

Description

Some firestore commands were incorrectly using two characters in their short option name. When passing two characters on the command line, only the first is actually parsed and checked, resulting in either unknown args or mismatched args.

Scenarios Tested

Success scenarios

• Create backup schedule with retention and recurrence
• Create backup schedule retention, recurrence and database (via -d)
• Create backup schedule retention, recurrence and database (via --database)
• List backup schedules with no arguments
• List backup schedules with -d
• List backup schedules with --database
• Update backup schedule with retention

Failure scenarios

• Create backup schedule without any args
• Create backup schedule without retention
• Create backup schedule with --retention but no value
• Create backup schedule without recurrence
• Create backup schedule with recurrence but no value
• Create backup schedule with recurrence but invalid value
• Create backup schedule with -d but no value
• Create backup schedule with --database but no value
• List backup schedule with -d but no value
• List backup schedule with --database but no value
• Update backup schedule with no arguments
• Update backup schedule without retention
• Update backup schedule with retention but no value

Sample Commands

firebase firestore:backups:schedules:create --retention 2w --recurrence DAILY
firebase firestore:backups:schedules:create --retention 2w --recurrence DAILY -d named-database
firebase firestore:backups:schedules:create --retention 2w --recurrence DAILY --database named-database

firebase firestore:backups:schedules:list
