[1.10.x] Exclude custom extra from pom dependency

[adpi2]

Fix sbt/sbt#7710

Custom extra attributes are not used for resolution. We remove them from POM extraDependencyAttributes, so they don't mess up the conflict resolution in Coursier (or Maven).

For instance this POM file contains too many dependency extra attributes: e:info.apiURL, e:info.versionScheme and e:info.releaseNotesUrl should be ignored

<extraDependencyAttributes xml:space="preserve">
+e:info.apiURL:#@#:+https://www.javadoc.io/doc/com.armanbilge/sbt-scala-native-config-brew_2.12/0.3.0/:#@#:
