[MC-228729] CanPlaceOn doesn't work with ink sacs/dyes used on signs

The bug

Glow inc sacs or dyes with the CanPlaceOn tag validly set can't be applied to signs in adventure mode.

Expected:
It works, just like putting a book in a lectern, stripping a log with an axe, etc. (use item on block)

Actual:
It doesn't work.

Steps to reproduce

Place down a wall sign
Go into gamemode adventure

Give yourself an glow ink sac with the following command

/give @p glow_ink_sac{CanPlaceOn:["minecraft:oak_sign"]}

Try using it on the sign

-> ❌ It doesn't work.

Not sure if it was faultily tested, but the steps to reproduce says to place a wall sign, but doesn't list the wall sign ID in the CanPlaceOn list; either change the ID or change the step to standing oak sign.

Can confirm in 1.21.4.

It affects all variants of signs, including standing/wall signs and ceiling/wall hanging signs.

The command should be updated to

/give @s glow_ink_sac[can_place_on={blocks:"#all_signs"}]
