update solochain to use #[runtime] (#5772)

# Description * This is part of [issue 5242](#5242), specifically getting solochain to use `#[frame::runtime]` * Furthermore, reinforced the convention of `Template` instead of `TemplateModule` ## Integration * Should be integrated into the `solochain` template and documentation ## Review Notes * Refactored `solochain` template from [construct_runtime!](https://paritytech.github.io/polkadot-sdk/master/frame_support/macro.construct_runtime.html) to [#[runtime]](https://paritytech.github.io/polkadot-sdk/master/frame_support/attr.runtime.html). * AFAIU `Template` is our new convention, and preferred over `TemplateModule`. # Out of scope * The [#[runtime]](https://paritytech.github.io/polkadot-sdk/master/frame_support/attr.runtime.html) documentation is still very rudimentary, and should ideally be expanded to explain the macro, both what it does and the input options. * Furthermore, suggest update [#[runtime]](https://paritytech.github.io/polkadot-sdk/master/frame_support/attr.runtime.html) documentation to replace `#[crate::runtime]` with `#[frame_support::runtime]` --------- Co-authored-by: Jan-Jan <111935+Jan-Jan@users.noreply.github.com> Co-authored-by: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io> Co-authored-by: Shawn Tabrizi <shawntabrizi@gmail.com> Co-authored-by: command-bot <>

       An optional attribute can be defined as `#[frame_support::runtime(legacy_ordering)]` to ensure that 
       the order of hooks is same as the order of pallets (and not based on the pallet_index). This is to support 
       legacy runtimes and should be avoided for new ones.
