fix(ci): Add symlink for libdl.so on Linux runner

This commit resolves a `System.DllNotFoundException` for `libdl.so` that
was causing all tests to fail on the Linux platform.

The .NET runtime on the GitHub `ubuntu-latest` runner was unable to locate
the dynamic linking library `libdl.so` in its standard search paths, even
though it is present on the system via the `libc6-dev` package.

This fix adds a command to the "Install Linux dependencies" step to create
a symbolic link from the actual library location to a path where the .NET
runtime can find it. This unblocks the native library loader and allows
the tests to run successfully.
