Drop 3.2 LTS line in SECURITY.md

Drop 3.2 LTS line to be aligned with https://quarkus.io/security/#supported-versions

[rsvoboda]

@gsmet could you look into this?

[gsmet]

It's not really my decision TBH. /cc @jmartisk who might know more about it.

[rsvoboda]

I should tag @maxandersen and @cescoffier from the start, sorry for pulling you into so many things @gsmet .

RHBQ 3.2 went EOL this week. I'm not that familiar with how the community LTS works, but right, I doubt we plan to fix CVEs in 3.2 now. Maybe the document could use some more clarification (for example, make a distinction between full support and maintenance support, to align with the product?) I can ask about that at the next security meeting...

[cescoffier]

Well, we can't maintain 3 streams. So now that 3.15 is out, 3.2 is out of support.

I was confused for a sec because I thought I already reviewed PR for this page - that one is over here: quarkusio/quarkusio.github.io#2136

Yes, 3.2 is now like any other 3.x's: no updates/maintanence planned.
