[PATCH 2/2] doc: update LTS release cadence

[Thomas Monjalon]

13/12/2021 17:48, Kevin Traynor:
> Regular LTS releases have previously aligned to DPDK main branch
> releases so that fixes being backported have already gone through
> DPDK main branch release validation.
> 
> Now that DPDK main branch has moved to 3 releases per year, the LTS
> releases should continue to align with it and follow a similar release
> cadence.
> 
> Update stable docs to reflect this.
