using maven-metadata.xml may show outdated version

### Current Behavior

for example `mqtt-client` latest version is 1.16
but dependency-track shows 1.12

because https://repo1.maven.org/maven2/org/fusesource/mqtt-client/mqtt-client/maven-metadata.xml says so.
but asking the appropriate api https://search.maven.org/solrsearch/select/?q=g:org.fusesource.mqtt-client
reveals
`"latestVersion":"1.16"`

### Steps to Reproduce

see latest version of `mqtt-client`

### Expected Behavior

1.16

### Dependency-Track Version

4.8.0

### Dependency-Track Distribution

Container Image

### Database Server

MySQL

### Database Server Version

### Browser
