MMM for 'ro' locale doesn't use monthsShort

[mariusa]

Describe the bug

monthsShort is properly defined in
https://github.com/iamkun/dayjs/blob/dev/src/locale/ro.js

and seems to be handled in
#457

but the short month for "Nov." is wrongly listed as "Noi":

require('dayjs/locale/ro')
console.log(
    dayjs()
        .locale('ro')
        .format('MMM')
)

Expected behavior
use monthsShort and output 'Nov.'

Information

• Day.js 1.8.14
• OS: linux
• Browser nodejs 12
