[FEATURE REQUEST] Nexus-Module - `version: 'latest'` broken for version-parts > 9

[tandibar]

We are using something like this to download the latest artifacts from our nexus:

deploy_artefact:
  nexus.downloaded:
    - artifact:
        nexus_url: {{ salt['pillar.get']('nexus_url') }}
        repository: 'some-nexus-repo'
        artifact_id: 'some-service'
        group_id: 'de.whatever'
        packaging: 'jar'
        version: 'latest'
    - target_file: /opt/some-project.d/some-service.jar

If the maven-metadata.xml of this artifact looks like this:

<metadata modelVersion="1.1.0">
  <groupId>wonderfull.group</groupId>
  <artifactId>foo-bar</artifactId>
  <versioning>
    <latest>1.22.0-dev.30</latest>
    <release>1.22.0-dev.30</release>
    <versions>
      <version>1.8.0-dev.7</version>
      <version>1.8.0-dev.14</version>
      <version>1.10.0-dev.15</version>
      <version>1.11.0-dev.18</version>
      <version>1.13.0-dev.20</version>
      <version>1.15.0-dev.21</version>
      <version>1.16.0-dev.24</version>
      <version>1.19.0-dev.26</version>
      <version>1.20.0-dev.27</version>
      <version>1.20.0-dev.29</version>
      <version>1.22.0-dev.30</version>
    </versions>
    <lastUpdated>20210701073016</lastUpdated>
  </versioning>
</metadata>

'latest' will evaluate to '1.8.0-dev.7' because of this line:

salt/salt/modules/nexus.py

Line 558 in 971dfb4

latest_version = max(versionList)

This is just a string-compare and not a semantic-version comparison.

I think it would make sense to use a library like semver or semantic-version for the comparison.
