Update Code to 1.124.2 (#7846)

Since this functionality requires information placed onto the request by
code-server (req.args) and Express (req.cookies), move the standalone
tests into the integration tests as the proxy can no longer run
correctly on its own without that context.

We could strip the header elsewhere or refactor in some way (pass in a
callback function for the stripping or something) but this seems like
the simplest and safest place at the moment to ensure we catch all uses
of the proxy.

In any case, I think it does lend more confidence to know we are testing
the proxy the way it will be used in practice.  The downside is some
additional complexity when setting up tests, but at the moment I do not
think that exchange is overly burdensome.

 ## Unreleased
 
+Code v1.124.2
+
+### Security
+
+- Strip code-server's session token from the cookie before proxying to a local
+  port. Previously, when you used built-in password authentication, the cookie
+  would be sent to the local proxied port, which meant if the service was
+  malicious and not already running as your code-server user it could use the
+  cookie to log into code-server and execute commands as your code-server user.
+
+### Changed
