Deprecated boost header

The Linux tests give the following warnings:

@marcfehling These warnings also happen in our GitHub actions.

Do we have any indication of how we get to this place?

[peterrum]

This was introduced by #13451.

[marcfehling]

We don't explicitly include any of the headers that trigger the warnings anywhere in the deal.II library.

I think this is a problem that comes from inside the boost library. Bumping the bundled boost version could fix these warnings.

[marcfehling]

This was introduced by #13451.

The warnings you refer to are different ones: #13451 (comment)

[luca-heltai]

This maybe resolved similarly to #13927

[tamiko]

The issue with this deprecated header warning is that the include chain you're seeing In file included ... is for the chain how the macro got defined and not indicative for what header is actually including the deprecated header.

[tamiko]

I will now try to find what is responsible for the warning on Debian and Ubuntu.

[tamiko]

This seems to be resolved with the latest change.
