I made a few minor tone changes in the description (we can't use "you" as a third-party). Overall, this is looking good, but I have one concern: AWS documents Support Life cycle on a patch version basis, while this page is using minor releases.

This causes issues wherever multiple patch releases are simultaneously supported:

VERSION	EOL
3.3.1	2024-09-11
3.3.2	2024-09-11

On 2024-09-01, both 3.3.1 and 3.3.2 clusters were supported. But the table currently lists a single 3.3 row, which has an EOL.

Since there aren't multiple patch releases supported right now, this works well though, but only for now. But we might have to split a row in the future, and that would result in a breakage (say if 3.6.2 was released tomorrow).

It would be better to avoid that breakage if we can split currently supported release cycles into patch-levels instead (So 3.4 -> 3.4.0, 3.5 -> 3.5.1 and so on). We can ignore EOL releases, which are okay to be merged.

Also, if we can check what 4.0.x really means in terms of patchlevel that will be great - Can we try creating a cluster and seeing what version it reports? Is it 4.0.x or 4.0.0, and whether AWS really means 4.0 as the release cycle here?
