[package] hdf5/1.12.1 still depends on zlib/1.2.11 while many other use zlib/1.2.12

Our software is built using conan. It depends, among others, on hdf5 and boost.
Both depend on zlib.
Recently boost/1.78.0 got updated from using zlib/1.2.11 to zlib/1.2.12 (9301eda)
After that we get an error during conan install:

ERROR: Conflict in hdf5/1.12.0:
'hdf5/1.12.0' requires 'zlib/1.2.11' while 'boost/1.74.0' requires 'zlib/1.2.12'.
To fix this conflict you need to override the package 'zlib' in your root package.

However, being new to conan, we couldn't figure out how to state the correct override in our conanfile.py to fix this issue.
Also I am unsure whether this is a good fix, as we would override the dependency even after the problem vanished.
Or can I state that I don't care about exact minor versions of zlib being used and let conan decide?

I guess the best solution would be to also update hdf5 to zlib/1.2.12?
As I understand it would be best to change all dependencys on a package simultaneously if a new version is to be used, as users may otherwise run into the same problem in the future?

Thanks alot for working on conan and helping me with this problem!

in your conanfile.py you could have something like this:

    def requirements(self):
        self.requires("boost/1.78.0")
        self.requires("hdf5/1.12.1")
        self.requires("zlib/1.2.12", override=True)

Otherwise there is #10179, but no progress for 2 weeks.
