chore(deps): bump @types/dateformat to ^5.0.0 in admin-panel
Because: - The @types/dateformat dev dependency in fxa-admin-panel is two major versions behind. This commit: - Updates @types/dateformat from ^3.0.1 to ^5.0.0 in fxa-admin-panel. - Updates yarn.lock to resolve @types/dateformat 5.0.3. - Keeps the runtime dateformat at ^4.6.3; the call signature is the same. Closes FXA-5371
