[BUG]: mp-units examples do not compile
Describe the bug
The examples https://compiler-explorer.com/z/81Ev7qhTd and https://compiler-explorer.com/z/Tsesa1Pvq given in the description of the mp-units library do not compile. Those examples use mp-units trunk which since the creation of the examples appears to have introduced breaking changes. Manually changing the version to 2.1.0 makes the examples compile again.
Steps to reproduce
Search for the mp-units library and follow the link to either of the examples.
Expected behavior
The examples compile.
The first example seems easy enough to fix, only the path of the header appears to have changed: https://compiler-explorer.com/z/d4qWza16q The second example seems to need a few more changes as it looks like text output was changed quite a bit. Appears to work with https://compiler-explorer.com/z/7xGe6zvYs but I am not entirely confident this is exactly in the spirit of the example. Perhaps @mpusz has some input.
Would it perhaps be an idea to fix the library version in the examples to a specific version instead of using trunk to avoid breakage in the future?

The example links can be changed here: https://github.com/compiler-explorer/compiler-explorer/blob/main/etc/config/c%2B%2B.amazon.properties#L4727
But yes, it would be more ideal to have links that have fixed versions of the library selected in them.
@mjacobse, Those two examples were taken from our docs. A working version can always be found at https://mpusz.github.io/mp-units/2.3/getting_started/look_and_feel.
