Dayjs returns Invalid Date

[srav09]

Describe the bug
Dayjs returns Invalid Date if the date entered by a user starts with day name.

Example code:

import * as dayjs from 'dayjs';
import 'dayjs/locale/fr';

 var customParseFormat = require('dayjs/plugin/customParseFormat')
 dayjs.extend(customParseFormat);
 var localizedFormat = require('dayjs/plugin/localizedFormat')
 dayjs.extend(localizedFormat)
 var day = dayjs;
 day.locale('fr'); //Using french locale

  text = 'vendredi 1 janvier 2021 11:40:39 heure' ;
  format = 'dddd D MMMM YYYY h:mm:ss A';
  day(text, format, 'fr'); 

Executing the above line(day(text, format, 'fr')) is throwing the below error. It works only if the day name is given after YYYY. Example: '1 janvier 2021, vendredi 11:40:39 heure'.

ERROR: M {$L: 'fr', $u: undefined, $d: Invalid Date, $y: NaN, $M: NaN, …}

Expected behavior
Dayjs should return correct Date if the date entered by a user starts with day name.
