Test on LTS and pre-release with new syntax 'lts' and 'pre'

[gdalle]

The new syntax 'lts' and 'pre' for GitHub actions adapts to the current LTS and pre-release versions. Pre-release is much more stable than nightly when it exists, so it's a good place to check for future issues

JET complains because of traits

[simonschoelly]

Isn't v1.10 the new lts? In that case we should still keep the check for the lower bound version v1.6 until we decide to raise that version in Project.toml.

[gdalle]

Agreed, I'll open a separate PR to bump the compat

[gdalle]

I made the JET tests slightly less sensitive (:typo pass instead of :basic pass) until we figure out the trait union split. See https://aviatesk.github.io/JET.jl/dev/jetanalysis/#JET.JETAnalyzer

@simonschoelly this is a very small change but it is necessary for the tests in 1.11 to actually be informative instead of always failing. If you have no objections I'd like to merge it?
