azure-pipelines: install libyang3 instead of libyang1 (#4578)

sonic-buildimage no longer builds the libyang1 debs (libyang_1.0.73,
libyang-cpp, python3-yang); it now builds only libyang3. Update the CI
deb install steps in azure-pipelines.yml and the dependency list in
README.md to install libyang3_*.deb and python3-libyang_*.deb instead,
using versionless globs. The libyang-cpp deb has no libyang3 equivalent
and is dropped.

Updated the deb install lists in azure-pipelines.yml (both Install Debian dependencies steps) and the dependency list in README.md, applying the following mapping:

libyang_1.0.73_amd64.deb -> libyang3_*.deb
libyang-cpp_1.0.73_amd64.deb -> removed (no libyang3 equivalent)
python3-yang_1.0.73_amd64.deb -> python3-libyang_*.deb
Versionless globs are used throughout so the CI does not need to track exact package versions.

The .semgrep/no-direct-libyang.yml guard rule was left unchanged; it forbids direct import libyang (routing through sonic-yang-mgmt instead) and is not a deb reference.

How to verify it
In the CI Install Debian dependencies steps, the dpkg -i commands now reference libyang3_*.deb and python3-libyang_*.deb, which match the debs produced by current sonic-buildimage. No libyang1 deb references (libyang_1, libyang-cpp, python3-yang) remain in azure-pipelines.yml or README.md.
