<h2>Fix logic of error handling for npm warning and uncaught exception</h2>
<p>In scope of this release we fix logic of error handling related to caching (<a href="https://github-redirect.dependabot.com/actions/setup-node/pull/358">actions/setup-node#358</a>) and (<a href="https://github-redirect.dependabot.com/actions/setup-node/pull/359">actions/setup-node#359</a>).</p>
<p>In the previous behaviour we relied on <code>stderr</code> output to throw error. The warning messages from package managers can be written to the stderr's output. For now the action will throw an error only if exit code differs from zero. Besides, we add logic to сatch and log unhandled exceptions.</p>
