Create the reference docs as part of the Developer Hub -> https://github.com/paritytech/polkadot-sdk/blob/9c2b3eaa8c05f4f25809e87f1890679261cd1e03/developer-hub/src/reference_docs/mod.rs#L94

The focus should be: Learn about all the advance ways to test your coordinate a runtime upgrade and data migration.

I'm going to make this reference docs for Runtime Upgrades, which encompasses migrations.

So it'll also supersede this page: https://docs.substrate.io/maintain/runtime-upgrades/

Runtime Upgrade ref docs and Single Block Migration example pallet (#…
12ce4f7 
…1554)

Closes paritytech/polkadot-sdk-docs#55

- Changes 'current storage version' terminology to less ambiguous
'in-code storage version' (suggestion by @ggwpez)
- Adds a new example pallet `pallet-example-single-block-migrations`
- Adds a new reference doc to replace
https://docs.substrate.io/maintain/runtime-upgrades/ (temporarily living
in the pallet while we wait for developer hub PR to merge)
- Adds documentation for the `storage_alias` macro
- Improves `trait Hooks` docs 
- Improves `trait GetStorageVersion` docs
- Update the suggested patterns for using `VersionedMigration`, so that
version unchecked migrations are never exported
- Prevents accidental usage of version unchecked migrations in runtimes

paritytech/substrate#14421 (comment)
- Unversioned migration code is kept inside `mod version_unchecked`,
versioned code is kept in `pub mod versioned`
- It is necessary to use modules to limit visibility because the inner
migration must be `pub`. See
rust-lang/rust#30905 and

https://internals.rust-lang.org/t/lang-team-minutes-private-in-public-rules/4504/40
for more.

### todo

- [x] move to reference docs to proper place within sdk-docs (now that
#2102 is merged)
- [x] prdoc
