Fails to use profile from workspace

[NiklasEi]

🐛 Bug description

When specifying a profile e.g. wasm-pack build --profile wasm-release a_crate, it will fail if the crate is part of a workspace and the workspace is not a package itself.

Error: failed to parse manifest: /home/code/project/Cargo.toml
Caused by: failed to parse manifest: /home/code/project/Cargo.toml
Caused by: TOML parse error at line 1, column 1

1 | [workspace]
  | ^
missing field `package`

🤔 Expected Behavior

wasm-pack should use the profile defined in the workspace Cargo.toml.

👟 Steps to reproduce

1. Create a workspace with a profile called wasm-release
2. Add a crate to the workspace
3. Try to build that crate with wasm-pack build --profile wasm-release <crate>
