[Bug]: Improve Email Validation & Add Missing ID/Name to Subscribe Form Field

[jatinkaushik-jk]

What happened?

I found a BUG 🐞

The "Subscribe with Email" form on the Opportunities page has two issues:

• The email field lacks an id or name attribute.
• Email validation allows invalid inputs like "example@email" without proper domain extensions (e.g., ".com", ".in").

Steps to Reproduce:

1. Navigate to the Opportunities page.
2. Enter an invalid email such as "example@email" in the subscription field.

Expected Behavior:

• The form should validate proper email formats (e.g., regex pattern requiring domain extensions like ".com").
• The email input field should have an id or name attribute for better accessibility.

Proposed Solution:

• Add proper id or name to the email field.
• Implement or update regex to validate email formats that include domain extensions (e.g., ^[\w\.-]+@[\w\.-]+\.\w{2,}$).
