[bug] missing documentation: semver_mode

[KUGA2]

Describe the bug

Documentations states:

package_id_unknown_mode: Define the mode when the relationship between packages is unknown. If it is not possible to deduce the package type, because there are no shared or header_only options defined, or because package_type is not defined, then, this mode will be used. The default for this mode is semver_mode (similar to Conan 1.X behavior).

https://docs.conan.io/2/reference/conanfile/attributes.html#package-id-embed-non-embed-python-unknown-mode

But semver_mode is not mentioned in this document and not explained elsewhere. What is semver_mode?

How to reproduce it

Thanks for pointing this out @KUGA2
