Update supported nvim versions

[hsanson]

Deprecate neovim 0.6 and support 0.11+

• Update default g:ale_use_neovim_diagnostics_api variable to has('nvim-0.7').
• Update ale-lint-file-linters documentation to mention 0.7+ instead of 0.6+
• Update Dockerfile to use 0.7.0 instead of 0.6.0
• update engine.vim check for has nvim-0.6.0
• update run-tests to use v0.7 and 0.10 instead of 0.6 and 0.9
• update ale-development.txt to mention 0.7.0 instead of 0.6.0
• update ale.vim to mention 0.7.0 instead of 0.6.0

Unfortunately the docker images used to run tests is unable to build neovim-0.9 or newer making this change more challenging than expected: Vimjas/vim-testbed#91

We can consider increasing the minimum to 0.7 and leave tests up to 0.8 instead of latest 0.10.

Update to this: I didn't attempt to fix the testbed to test with newer Neovim versions, but I did change the minimum supported version we test with to 0.7.

@hsanson If you can publish your patches to vim-testbed I'll create a dense-analysis repo for it, publish the Docker image, and we can use that image for updated ALE tests with the latest Neovim. I'll make you an admin of that repo.

@w0rp on vim-testbed the only change is to update the base FROM image in the Dockerfile:

On ALE this is my failed attempt:

• Update testbed/vim image to 25 that is a version I build locally using the updated Dockerfile above.
• Remove python2 that is no longer available.
• Add lua5.1-lpeg package needed to build neovim 0.10+

With these changes I can get the image to build and tests to run on neovim 0.10.4 but the test fails for reason I have not looked further.

I have a branch with the changes on my local. I have not submitted a PR since vim-testbed:25 only exists on my local.

Thanks @hsanson. I might give it a shot.
