Sinon 10 breaks Internet Explorer 11 support

[rsnigel]

Describe the bug
Sinon 10 is using Template literal strings (https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Template_literals) which is not supported by IE11.

To Reproduce
Steps to reproduce the behavior:

Looking at https://sinonjs.org/releases/sinon-10.0.1.js assert.fail(`${method} is not a function\`); is used.
In 9.x at https://sinonjs.org/releases/sinon-9.2.4.js assert.fail(method + " is not a function"); is used, which is working with IE11.

Expected behavior
Do not use template literals or proper transpiling.

We dropped support for IE11 with version 10: https://github.com/sinonjs/sinon/blob/master/CHANGELOG.md#1000--2021-03-22. Going forwards, we only support evergreen browsers.

All prior versions still work, of course, so you are not exactly stuck 😄

In that case please update the documentation https://sinonjs.org/releases/latest/ which mentions Internet Explorer 11 as a supported runtime.

Great catch! That is indeed out of date.

@mroderick I don't think we should keep any of that text block. It is woefully out of date and even worse: misleading - we haven't verified Sinon 10 in any of those! Might have been true for Sinon 3 or something :)

I agree. Let's improve that!
