Fetch errors should be shown when subsequent errors occur

[smoelius]

Fetch errors should be preserved here:

dylint/dylint/src/metadata/cli/mod.rs

Lines 246 to 253 in 958907f

	let _output = dylint_internal::cargo::fetch("dummy package")
	.stable(true)
	.build()
	.args([
	"--manifest-path",
	&path.join("Cargo.toml").to_string_lossy(),
	])
	.logged_output(false)?;

Then, if a subsequent error occurs, the fetch error should be shown.

Example where a subsequent error could occur:

dylint/dylint/src/metadata/cli/mod.rs

Lines 327 to 330 in 958907f

	accessed
	.into_iter()
	.next()
	.ok_or_else(|| anyhow!("Could not determined accessed subdirectory"))
