Add shared credentials for Feedbin (feedbin.me → feedbin.com)

[mangeshraut712]

Bar check: This meets the shared-credentials bar. feedbin.me and feedbin.com are the same Feedbin account. https://feedbin.me/login redirects to https://feedbin.com/login, which returns 200 and includes a password field. A nonexistent path on that host returns 404. A password saved on feedbin.me is the password for that same account on feedbin.com.

feedbin.me is marked obsolete because the host redirects to feedbin.com. The redirect is HTTP 301.

Evidence, checked live:

• https://feedbin.me/login → 301 https://feedbin.com/login → 200, title Feedbin, with input type="password" name="password".
• https://feedbin.com/login → 200 with the same password field.
• https://feedbin.com/this-path-should-not-exist-4a36 → 404, body text 404 Not Found.
• https://feedbin.me/ → 301 https://feedbin.com/.
• https://feedbin.me/this-path-should-not-exist-4a36 → 301 to feedbin.com, then 404.

Overall Checklist

for shared-credentials.json
