Fixed escaping of properties for azure-functions-http archetype

[mswiderski]

fixes escaping of properties to not have them expanded by archetype information to avoid following in generated app

    <azure.functions.maven.plugin.version>1.9.1</azure.functions.maven.plugin.version>
    <functionAppName>quarkus-azure-functions-http-archetype-20211122143239183</functionAppName>
    <functionAppRegion>westus</functionAppRegion>
    <functionResourceGroup>java-functions-group</functionResourceGroup>
    <function>quarkus</function>
    <stagingDirectory>/data/home/gsmet/git/quarkus-release/work/quarkus/extensions/azure-functions-http/maven-archetype/target/azure-functions/${functionAppName}</stagingDirectory>
    <quarkus.package.type>uber-jar</quarkus.package.type>
  </properties>
  <dependencies>

and similar in the plugins

  <resources>
    <resource>
      <directory>/data/home/gsmet/git/quarkus-release/work/quarkus/extensions/azure-functions-http/maven-archetype/azure-config</directory>
      <includes>
        <include>host.json</include>
        <include>local.settings.json</include>
      </includes>
    </resource>
  </resources>
</configuration>
