OKR Q2 2024: Objective 1: Improving the Polkadot developer experience KR: New dev templates are shipped as independent repositories automatically upon each stable release with source of truth in polkadot-sdk

Problem: https://github.com/paritytech/polkadot-sdk/issues/3155 The existence of substrate-developer-hub in itself is questionable in my opinion. It is not well maintained, and I much rather everything to be in /paritytech, and ideally in polkadot-sdk repo.

Details From @kianenigma What we suggest doing is the following:

• Bring all templates of polkadot-sdk under one folder. /templates/solo-chain, /templates/parachain and /templates/minimal are the main 3. These are the source of truth and always kept up to date.
• Create repositories corresponding for each, called polkadot-sdk-solo-chain-template, polkadot-sdk-solo-parachain and polkadot-sdk-minimal-tempalte.
• Write a script that receives a commit hash somewhere in the stable branch as input, and mirrors the templates into their corresponding repo. This script needs to replace all Cargo.toml files to use the released crates.
• We run the above script upon each update of stable branch, i.e. every 3 month.

I don't see any reason to publish them, please make a PR to the base repo and mark them as unpunlish, thank you :)

@Morganamilo has yanked the crates, so this problem is already solved :) And in the repo they're already marked as unpublish.

After a small fix in psvm, the synchronization has worked with no issues.

All templates got automatically updated to 1.12.0.

Closing as completed - I'll still try to help with the source templates, but the automation of synchronization is done.
