Mention other potentially useful test runner options in `exercises/shared/.docs/tests.md`

[angelikatyborska]

Extend exercises/shared/.docs/tests.md with the mention of those useful flags:

• To run tests in order: --seed 0
• To run tests until the first failure: --max-failures 1
• To run a single specific test: test/some/particular/file_test.exs:12
• anything else?

Also we need to fix the text about pending test to explain that only practice exercises have pending test.

Maybe --listen-on-stdin too? I use it a lot.

And definitely add a link tohttps://hexdocs.pm/mix/1.12/Mix.Tasks.Test.html#module-command-line-options for more options.
