Direct people correctly to find appropriate support

[omnat]

Current behavior: 'Send Feedback' redirects to support page where user can submit a request, which sends a ticket to the support team on Zendesk.
Expected behavior: "Send Feedback" (previously meant for beta stage) to now be changed to "Request a Feature", this link should direct to the Community Feature Requests subcategory: https://community.metamask.io/c/feature-requests-ideas/

'Get Help' correctly redirects to the support site where users can find articles to find help, and submit a request to the support team if their query is unanswered with the knowledge base.
