Organization invitations should ignore capitalization

[Tpuljak]

Describe the bug
Currently, if someone with the email daytona.test@daytona.io is signed up and another user invites them to the organization by inputing Daytona.Test@daytona.io, daytona.test@daytona.io will receive the invitation email (because capitalization is ignored when sending emails) but will not be able to accept it nor will it show up in their dashboard.

To Reproduce
Steps to reproduce the behavior:

1. Send an organization invite to someone with different capitalization in their email
2. They will receive the invitation email
3. They won't be able to join nor will it show up in their invitation dashboard

Expected behavior
It should show up in the invitation dashboard page and they should be able to accept the invite.
