Custom target directory causes generated rustdoc files to overwrite each other

[tonowak]

Steps to reproduce the bug with the above code

cd /tmp
git clone ssh://git@github.com:obi1kenobi/cargo-semver-checks
cd cargo-semver-checks
mkdir -p .cargo
echo '[build]\ntarget-dir = "/tmp/target"' > .cargo/config.toml
cargo run semver-checks check-release --manifest-path ./test_crates/enum_missing/new/Cargo.toml --baseline-root=./test_crates/enum_missing/old/Cargo.toml

Actual Behaviour

It ends successfully without reporting any issues.

Expected Behaviour

It should find a semver breaking issue.

Additional Context

I think this bug happens when the binary is in any other place other than in the default path (not only by passing a custom path to the built binary).
