Update to go 1.18.6 to address CVE-2022-27664, CVE-2022-32190

From the mailing list:

We have just released Go versions 1.19.1 and 1.18.6, minor point releases.
These minor releases include 2 security fixes following the security policy:

- net/http: handle server errors after sending GOAWAY
  A closing HTTP/2 server connection could hang forever waiting for a clean
  shutdown that was preempted by a subsequent fatal error. This failure mode
  could be exploited to cause a denial of service.

  Thanks to Bahruz Jabiyev, Tommaso Innocenti, Anthony Gavazzi, Steven Sprecher,
  and Kaan Onarlioglu for reporting this.

  This is CVE-2022-27664 and Go issue https://go.dev/issue/54658.

- net/url: JoinPath does not strip relative path components in all circumstances
  JoinPath and URL.JoinPath would not remove `../` path components appended to a
  relative path. For example, `JoinPath("https://go.dev", "../go")` returned the
  URL `https://go.dev/../go`, despite the JoinPath documentation stating that
  `../` path elements are cleaned from the result.

  Thanks to q0jt for reporting this issue.

  This is CVE-2022-32190 and Go issue https://go.dev/issue/54385.
