Use Eask for CI

[jcs090218]

This is the same PR with emacs-lsp/lsp-ui#700 and emacs-lsp/dap-mode#596

Special changes to this PR:

• I have temporary disabled the ert test due to this error https://github.com/jcs-PR/lsp-mode/runs/6003823570?check_suite_focus=true#step:13:1168

Unknown key: :something-unrelated.  Available keys: (:start :end)

It seems like I couldn't evaluate the test script directly ./test/lsp-protocol-test.el? Did I miss something?

The failing test is written like that:

    (should-error (pcase particular-range
                    ((MyRange :something-unrelated)
                     t)
                    (_ nil)))

So the error means the test should pass. I am not quite sure why this happens. Maybe the ci is running in a mode that means any error should break the job.

Ah.. I think loading ERT shouldn't trigger any error. Now tests can be operated without stopping.

It leads to some interesting results:

ubuntu-latest, 27.1 (Cask)

LSP :: Shutdown pyls:3498 since folder /home/runner/work/lsp-mode/lsp-mode/test/fixtures is removed...
..............................................................

Ran 62 tests in 20.910 seconds

ubuntu-latest, 27.1 (Eask)

Ran 75 tests, 63 results as expected, 12 unexpected (2022-04-15 07:23:31+0000, 23.612242 sec)

12 unexpected results:

Why are there tests 75 in Eask but only tests 62 in Cask? 😕 The tests seem to be accurate since I cannot get past these tests on my machine as well (Windows, Emacs 29.0.50).

Total of 80 ert-deftest appeared in the project, and 5 redefined tests. I assumed 75 is the correct number of the total test cases?
