disabled ways-to-give route

[danielfmiranda]

Description

Closes #1770

Per request of the Donate Team, we are disabling the existing WaysToGive route from the donate stack, and implementing a redirect in its place so when users visit donate.mozilla.org/en-US/ways-to-give, they get redirected to foundation.mozilla.org/en/donate/ways-to-give instead!

Steps to test

1. Visit https://donate-wagta-1770-hide--bjnuwq.herokuapp.com/en-US/ways-to-give/
2. Note that you now receive a 404 page instead of the "Ways-to-give" page.
3. If the 404 Page is appearing, testing is complete! The redirect has already been implemented on production.
4. If you would like to test the redirect, visit https://donate.mozilla.org/ways-to-give/. Note that it redirects you to https://foundation.mozilla.org/en/donate/ways-to-give/

PR looks good to me. Thanks @danielfmiranda!

Do you know if there will be a prod push for donate stack before the break? Asking because I see that this PR is set to be merged into main. If we don't plan on having another prod push, it might be safer that we create a feature branch and merge changes into there so that we can keep main clear in case anything comes up (e.g., needing to deploy a hotfix 🤞🏻 )

Hi @mmmavis thanks again for the review!

Regarding your question about the prod-push and the code freeze. Tyler and I have discussed in this slack thread that since this change is so minimal and on the now deprecated donate stack, we are OK to merge this in and to push to production.
