fix: missing types when linting showcase-sdk (#1309)

## Proposed change

When linting showcase-sdk, if the build of dependent packages was not
done (which is the case in CI), types of dependent packages are
interpreted by typescript as `any` because the tsconfig in showcase-sdk
overrides paths defined in the root of the repository and, as a
consequence, typescript does not find the source files defining the
types.
