Corrected NTP_KEY list name in SONiC Yang (#23401)

sonic-buildimage : #23401
sonic-mgmt-framework - sonic-net/sonic-mgmt-framework#150
sonic-mgmt-common - sonic-net/sonic-mgmt-common#182

Why I did it
To support openconfig system module in sonic as per HLD : sonic-net/SONiC#1790
Some sonic yang changes are required, which is done under this PR

sonic-mgmt-common PR # sonic-net/sonic-mgmt-common#179

Work item tracking
NA

How I did it
In sonic-ntp.yang, list name was not as per ABNF rule, which was causing cvl errors, fixed the same
/ntp:sonic-ntp/ntp:NTP_KEY/ntp:NTP_KEYS_LIST
to
/ntp:sonic-ntp/ntp:NTP_KEY/ntp:NTP_KEY_LIST
How to verify it
Ran all test cases in sonic-utilities and sonic-mgmt-common to ensure changes work fine
