Set julia compat to v1.10

[jishnub]

Since v1.10 is the LTS now, we may focus development only on v1.10+. Versions of this pacakge <v1.15 would continue to be compatible with julia v1.6.

I think it would be a good opportunity to also clean up existing VERSION checks in the package and the tests.

It actually seems that Julia < 1.10.10 is completely untested at this point:

FillArrays.jl/.github/workflows/ci.yml

Lines 40 to 43 in f160c66

	version:
	- 'lts'
	- '1'
	- 'pre'

You might want to test min as well (which currently would be 1.6.0 and with this PR 1.10.0, in contrast to lts which is 1.10.10).

I think testing 1.10.0 in addition to 1.10.10 is excessive. If a bug is ever triggered only in 1.10.0 it's not a good use of anyones time to fix it.

[devmotion]

If a bug is ever triggered only in 1.10.0 it's not a good use of anyones time to fix it.

In principle, you don't have to fix anything apart from correcting the Julia compat entry: If the package does not support 1.10.0, it should not be declared to be compatible with 1.10.0.

Currently, the problem is even more sever as not testing min means that not only versions 1.10.0 - 1.10.9 but all of 1.6.0 - 1.10.9 are not tested. If you'd like to reduce CI times, IMO it would actually be better to skip pre and/or to test min and 1 instead of lts and 1 (based on the assumption that if e.g. tests pass with 1.10.0 they most likely also pass with 1.10.10).

[dlfivefifty]

I agree that in theory we should be testing v1.6.x right now. But one can argue if a version of Julia is no longer supported then there shouldn't be an expectation that packages continue to work

I'm less worried about CI time than I am additional developer burden. Every extra test is an extra point of failure...
