Release Page: Fix Main Illustration Flash

[Arthi-chaud]

When using Chrome, on the release page, when the track changes, the illustration in the page header gets reloaded, which causes a flash.
This is caused by the use of usePlayerContext.

• The flash should not happen
• There should be two hooks: one to get the player state, and one to change it.
  • Changes in the player's state should not make the use of the second hook to reload
