Removes reference to masonry values

[pepelsbey]

Description

⚠️ Not a proper display: grid-lanes docs PR yet, just a cleanup for old masonry spec leftovers.

• Removes outdated grid-template-*: masonry values
• Removes irrelevant masonry-auto-flow note

Motivation

To remove confusion from the Masonry guide and reference pages.

Additional details

The only old masonry implementation remains in Firefox behind the flag and has never been publicly available. It probably shouldn’t have been documented on MDN in the first place.

The new display: grid-lanes implementation has been shipped in Safari and is being worked on in Chrome.

@pepelsbey, there's another PR in the works: #44436 - there will be a conflict in the masonry_layout guide file

[pepelsbey]

@dipikabh I dropped the changes to the guide and left only grid-template-*: masonry values removals.
