Replace moment.js by date-fns

[hiendv]

Reasons:

• Immutability
• Tree-shaking / Bundle size
• Clean API

Related:

• Do not require moment.js chartjs/Chart.js#4303
• Add a brief comparison with Moment.js? date-fns/date-fns#275

Old code:
created: new Moment(new Date(this.info.created_at).valueOf()).format("LTS ll"),
updated: new Moment(new Date(this.info.updated_at).valueOf()).format("LTS ll")

Updated code:
created: DateFNS.format(DateFNS.parse(this.info.created_at), "hh:mm:ss A MMM Do YYYY"),
updated: DateFNS.format(DateFNS.parse(this.info.updated_at), "hh:mm:ss A MMM Do YYYY")
