Add support for new NodeSource repository + Node 18.x

[stissot]

Description

The NodeSource project has launched a new DEB & RPM unified repository under the nodistro codename, using a new GPG signing key. The APT repository (Debian, Ubuntu) should also not use deprecated apt-key anymore. Also this cookbook should at minimum support test installing NodeJS 18.x (currently supported) and drop 17.x (not supported).

Issues Resolved

• Default install Node 18.9.1, using Node 18.x new nodistro package repository
• Repo recipe: adjust to match 18.x manual install recommended by NodeSource
• Add support for Alma Linux 9
• Drop support for Amazon Linux 2, CentOS 7 (unsupported by NodeSource 18.x)
• Repair the broken Inspec test commands

Check List

• [x] A summary of changes made is included in the CHANGELOG under ## Unreleased
• [x] New functionality includes testing.
• [x] New functionality has been documented in the README if applicable.

Remarks

• We should add tests with Amazon Linux 2023 (already supported by NodeSource 18.x) when Chef and Bento support it:
