reusable modal component

[nagarajpandith]

• currently modal is being used at 5 places but each of them have their own implementations
• create a reusable modal component which can be used on all these 5 and also for future implementations
• replace the modals with the new component in below 5 files and delete their old modal implementation files (if any)
  • src > components > event > index.tsx
  • src > components > profile > index.tsx
  • src > pages > admin > events.tsx
  • src > pages > admin > register.tsx
  • src > pages > admin > teams.tsx
• if applying animations, please use top to bottom slide used on /events page modal
