feat: Add contact management feature with validation

Fix issue #1

Add a page that allows users to add their name, phone number, and email address

When this information is submitted, a POST request should be made to /resume/experience on the server in the following format:

{
  "name": "Jane Doe",
  "phone": "+1 555 123 4567",
  "email": "jane@example.com"
}

@Pradyuman7 I realized the old pr was approved but was not merged, and I deleted the branch that closed the other pr, so here is another pr to fix that.
