How long will Rails 5 be supported?

I'm sorry if this is the wrong place for this question, but I wasn't sure where else to ask. Is there a timeline for how long Rails 5 will be supported?

Here's details on the support / maintenance policies for Rails. https://guides.rubyonrails.org/maintenance_policy.html

Only the latest release series will receive bug fixes. When enough bugs are fixed and its deemed worthy to release a new gem, this is the branch it happens from.

The current release series and the next most recent one will receive patches and new versions in case of a security issue.

For severe security issues all releases in the current major series, and also the last release in the previous major series will receive patches and new versions. The classification of the security issue is judged by the core team.

So that means Rails 5.2 will continue receiving security updates until Rails 6.1 is out. Rails 5.1 and earlier are no longer supported.
