[Frozen - Do not action] Remove RHEL7 and Debian 10 from the support matrix for APM server

Aligning with Elastic Agent on

• https://github.com/elastic/ingest-dev/issues/3606

Pausing this until we get more understanding from support on where customers are.

@mlunadia for profiling we would like to include Debian 12 and RHEL 9.
Is Agent going to do the same? Should APM server do it?

[mlunadia]

@inge4pres For profiling I think is @teknogeek0 's call.

I've learnt there isn't an aligned support policy for our stack so we will need to speak with support to understand what works best and revisit this.

I don't have an opinion on this one. Would be good to get more info.
