Parachain template XCM config is off

[franciscoaguirre]

Much like I reported for r0gue's base-parachain template, the XCM configuration in our parachain template is very outdated and with bad defaults:

• HashedDescription should be used as the latest converter
• DenyReserveTransferToRelayChain shouldn't be used anymore
• The asset transactor should match Here instead of Parent
• execute should be enabled by default

Additionally, with AHM, we should change the config that gives the relay root unpaid execution and change it to Asset Hub. Also, I believe the fellowship is not using the executive body anymore. The fellowship entities that could be given free execution are here: https://github.com/polkadot-fellows/runtimes/blob/1f98363a131ce68634fa8fa831c0dd1c35945af3/system-parachains/asset-hubs/asset-hub-polkadot/src/xcm_config.rs#L272. Even then, maybe we don't want this for a template.
