doc: update LTS maintenance to 3 years

The existing official policy was to maintain LTS releases for 2 years. 19.11 and 20.11 LTS releases were maintained for 3 years and there was not significant issues caused by code divergence from main etc. Update the policy to indicate 3 years maintenance for LTS releases, but note that it depends on community support.
