Flash detect says I do not have flash when i'm running ruffle

[CoolDino1]

Describe the bug

The flash detect on this page (http://kingscall.org/start.html) says 'It appears you do not have Flash! Please go here to get it.' even though I am running Ruffle.

Expected behavior

I do not know what it should have done otherwise but I know it should not say I do not have Flash

Affected platform

Browser's extension

Operating system

Windows 10

Browser

Mozilla Firefox 96.0.2

This also happens on Basilisk with the official Flash Player - a JS script on this website tries to detect the version of Flash but as it's poorly written, any version above 6 is not recognized.

Similar to #5613 (comment) and somehow related to #819.

Looks like we need to make the player version reported by Ruffle's JS plugin polyfill customizable. #8961 only covered the player version reported to movies via ActionScript.
