[BUG] [5.2]: 'grant select on da380_now to public;' failing

[os10000]

Many thanks to you all for building & maintaining JSQLParser!!!

Failing SQL Feature:

• the grammar defines 'UsersList' containing n 'RelObjectName'
• 'RelObjectName' in grammar diagram 5.2 does not explicitly include 'public'
• 'RelObjectName' allows 'RelObjectNameWithoutValue'
• 'RelObjectNameWithoutValue' allows 'S_IDENTIFIER' -- that would work
• yet, it naturally compares it to tokens first and rejects it

SQL Example:

• 'grant select on da380_now to public;'
• net.sf.jsqlparser.parser.ParseException: Encountered unexpected token: "public" "PUBLIC"
  at line 1, column 30

Software Information:

• compiled with JSqlParser version 5.1
  com.github.jsqlparserjsqlparser5.1
• postgresql does accept the statement

alternative attempt (add 'table' after 'on'):

• 'grant select on table nexpay_2_faa_tbl to public;'
• Encountered unexpected token: "nexpay_2_faa_v" <S_IDENTIFIER> at line 1, column 23
