[BUG] --silent suppresses output from run commands

[G-Rath]

Previously in pre-npm 7 --silent would only silence output from npm, meaning that run would still output the output from whatever is being run.

Now, it silences everything, meaning we can't use --silent to silence the npm ERR! messages that follow whenever a command fails.

Current Behavior:

> npm run typecheck --silent

Expected Behavior:

> npm run typecheck --silent

src/audit.ts:137:13 - error TS2345: Argument of type 'AuditMetadata | NpmAuditMetadataV2' is not assignable to parameter of type 'AuditMetadata'.
