[feature] add proper requires to conan search output

[fulara]

This possibly could be a bug submit :)

Currently (in 1.24 ) when building package and we have missing prebuilt conan will spew output like this:
cant find a .. settings: "...", "options: "...", requires: "..."

However conan search reference .. only outputs valid options, settings.
requires output is slightly off - its basically a full_requires - not sure why decision was made to print [full_requires] in place of [requires]

Making requires print the original value would allow for direct matching between these two outputs, tracking exactly what our build matrix is missing to satisfy criteria of conan install.

Scanning the codebase:
https://github.com/conan-io/conan/blame/8f5e997660bd265789f48bd26c54797f5f74067f/conans/model/info.py#L469
We can see a direct assignment requires = full_requires - and also hardcoded semver_direct_mode ?

Anyway,
It would be great if conan info .. would print it in the form available in conaninfo.txt so something like:
1.Y.Z if only major version is of interest.

Closing,

I just had a realisation that the content of this issue is slightly untrue.
I will reword this and reopen it later
