Another rewrite of the WASM apology message.

Browse Source 
Now I've had a chance to collect some more data from browser users,
it's got a list of browsers in which we've definitely seen the WASM
puzzle working (so that if _your_ instance of one of those browsers
fails, you should check it for problems at your end, like
configuration details or overzealous web filtering software), and some
thoughts about what to report.

The result is a lot longer than the previous error message, so I've
put the bulk of it in a <details>. That way it won't look so silly
when it initially flashes up while things are loading.

<p>Most modern browsers should support WASM. I've had reports of success from:
<ul>
<li>Firefox 87.0</li>
<li>Chrome 89.0.4389.114</li>
<li>Safari 14.0.3 (16610.4.3.1.7)</li>
<li>Edge 89.0.774.68</li>
<li>Opera 75.0.3969.149</li>
</ul></p>
<p>If this puzzle isn't working in one of those browsers (or a later
version), check to see whether you have any local configuration that
might have turned off WebAssembly completely, or some kind of blocking
software that might have prevented the WASM code from being downloaded
in the first place.</p>
<p>(For example, in Firefox, it's possible to turn off WASM completely
by setting <code>javascript.options.wasm</code> to <code>false</code>
in the <code>about:config</code> interface. If you've done that, or
something analogous in another browser, this puzzle won't run.)</p>
<p>In other browsers, the problem might be that WebAssembly isn't
supported at all (for example, Internet Explorer 11), or that a
browser update is needed.</p>
<p>If you think that your browser <em>should</em> support WebAssembly,
but this puzzle still isn't running, then please report the problem,
including <strong>as much diagnostic information as you can
find</strong>.</p>
<p>In particular, try opening your browser's Javascript error console
and then reloading this page, and tell me if it reports any error
messages.</p>
