chore: migrate to @nextcloud/eslint-config 9

Its ESLint 10 reads a flat config only, so .eslintrc.cjs becomes eslint.config.js,
whose rules apply to the app sources, leaving the exemptions version 9 grants test
files in place. The lint workflow watched .eslintrc.* and .eslintignore, neither of
which exists any more, and webpack.js was the last place configuring ESLint the old
way: nothing declares its dependencies, so it could not run at all.

The import rules are gone from the shared config, so 'import/extensions' goes with
them, as do the babel parser options and the appVersion global the sources do not
use, which the shared config declares anyway. 'no-console' was built into the old
config and is now spelled out.

The sources follow what the new rules ask for: sorted imports, blank lines between
multi line component options, and camel cased attributes and events in templates.
Unused callback parameters are gone, one rule asks for the ellipsis character in a
translatable string, so 'Loading...' became 'Loading…', and the dashboard component
is called GithubDashboard, because a name of one word can collide with an HTML
element.

Two findings needed a decision. NcPopover was given focusTrap, which
@nextcloud/vue 9 does not declare any more, so asking for the focus trap to be off
did nothing and the popover kept building a trap it does not need. The .native
modifier of three mouse listeners is one the Vue 3 compiler drops while keeping the
listener, so removing it changes nothing; that holds for these three, not for key
events, where the modifier is compiled as a key name and swallows the handler.

Folding a comment and the popover of a comment author had no test, and now have one.
eslint.config.js has no place in the released archive, and the .eslintrc.js the
packaging lists named never existed here.

The widget passed its label to the dashboard component as 'showMoreText'. The prop is
called showMoreLabel, so the link under a full widget read 'More items …' instead of
what the widget asked for.

The lint scripts passed --ext, which ESLint 10 ignores, and the change filter of the
build did not watch the config file the build now reads.
