versioning – Regex for self hosted renovate bot to fetch linuxserver.io stable images

I’ve setup the renovate selfhosted bot. Since linuxserver.io has different schemas of creating docker tags, i’ll switched to regex.

{
  "$schema": "https://docs.renovatebot.com/renovate-schema.json",
  "extends": [
    "config:base",
    "docker:enableMajor"
  ],
  "packageRules": [
    {
      "packagePatterns": ["^ghcr.io\\/linuxserver\\/"],
      "versionScheme": "regex:MYFANCYREGEX"
    }
  ]
}

But I need help getting the regex up and running.
I created a regex 101 with unittest and example – here

100.200.300
100.200.300.7068-ls170
v100.200.300-ls213
version-100.200.300
version-100.200.300-ls180
version-100.200.300.11111
100.200.300.7068-ls170
nigthly-100.200.300  -> not stable, no match
nightly-100.200.300.3604-ls587  -> not stable, no match
100.200.300-development -> not stable, no match
100.200.300-develop -> not stable, no match
100.200.300-nigthly -> not stable, no match

I’m somehow not able to exclude matches containing something -> (?! or ^)

How should I change the regex to only get stable builds and the image updates (ls/buildnumbers)
