Diff: 3.5.0...3.6.0

`.substr()` is deprecated so we replace it with `.slice()` which works
similarily but isn't deprecated.

A few notes:

- the certificates were recreated because Node.js 18 includes OpenSSL
v3, which has deprecated support for some legacy ciphers (like RC2)

- eiows currently fails to build on Node.js 18, so the tests are
temporarily skipped

Before this change, receiving an HTTP2 upgrade would make the server
crash:

> Error: read ECONNRESET
>    at TCP.onStreamRead (node:internal/stream_base_commons:217:20) {
>  errno: -104,
>  code: 'ECONNRESET',
>  syscall: 'read'
> }

This can be reproduced with Node.js v14.15.3, v16.18.1 and v18.12.1.
