fix(core): skip delay when switching between grouped tooltips

[sampotts]

Summary

• shouldSkipDelay() returned false when #isOpen was true — this prevented instant tooltip switching because the previous tooltip's async close hadn't fired yet when the next tooltip checked the delay.
• HTML ContextProvider had no initialValue — @lit/context consumers without subscribe: true only get the value at request time. Since TooltipGroupElement set the value in update() (async), tooltips connected before that got undefined and never received the group reference.

Closes #898

Test plan

• pnpm -F @videojs/core test src/core/ui/tooltip — all 21 tests pass
• pnpm typecheck — clean
• pnpm lint — clean
• Manual: hover between grouped tooltips in video/audio skins — second tooltip should appear instantly (no 600ms delay)

Pull request overview

Fixes grouped tooltip “hysteresis” so switching between tooltips in the same group can open instantly, and ensures tooltip group context is available synchronously to context consumers.

Changes:

• Update TooltipGroupCore.shouldSkipDelay() to skip delay while another tooltip in the group is still open.
• Provide an initialValue for the tooltip group ContextProvider so early consumers don’t receive undefined.
• Adjust unit tests to reflect the updated skip-delay behavior.

Looks like just a test name fix, otherwise looks good!
