Does not support workspace inheriting

[workspace.dependencies]
foo = { package = "bar" }

[dependencies]
foo = { workspace = true }

only iterated the dependencies inside the package, once a package renamed its dependency in workspace level, the searching logic doesn't work

Seems like the nasty workaround is to include package attribute, which is ignored by rust compiler (and throws warning), but is taken into consideration by this macro - see: https://github.com/paritytech/ink/pull/1835
