Bump php dependencies (and other minor tweaks)

[stronk7]

Bump a bunch of php dependencies to latest ones

Just update to current ones, automatically, without changing
any composer.json requirement.

Fixes #332 (and #333, just saw that one).

And, also, 3 more commits:

• Re-generates the CLI docs which features were changed by Use general stylelint task in grunt command #320. <-- (just a detail)
• Bump GHA to postgres 14, that is a requirement for Moodle 5.0. <-- (self tests)
• Remove the PHPUnit --verbose option from Moodle >= 5.0 runs. <-- (impacting!)
