Reopens #19081

I stopped working on that PR because I found out that you usually do not have the lambda:listLayerVersion policy for layers you do not own. So I thought this whole datasource didn't make any sense. But in fact it is useful as we found out in a team internal discussion today:

• you can use it to update lambda layers you own
• you can ask the maintainer of the layer you do not own to add the respective permission so Renovate can list the version numbers as well

aws lambda add-layer-version-permission \
    --layer-name my-layer \
    --statement-id xaccount \
    --action lambda:ListLayerVersions  \
    --principal 123456789012 \
    --version-number 1

Still have to work on the documentation

Still struggeling with the pnpm-lock.yaml. How can I regenerate the file so it includes my changes?

@viceice Is this assumption correct? If not: how to catch this error?

try {
  FilterParser.parse(xxxx);
} catch (e) {
  // log error and return null
}

Looks ugly and I guess there is a better option. Checking the existing source, I didn't find any.
