Expand the Metal Gear Solid tags to reflect 35 character tag limit

Question

Since the 35 character tag limit is long enough for all of the full game names in the Metal Gear Solid series, the following tags should be renamed:

• metal-gear-solid-2 → metal-gear-solid-2-sons-of-liberty
• metal-gear-solid-3 → metal-gear-solid-3-snake-eater
• metal-gear-solid-4 → metal-gear-solid-4-guns-of-patriots
• metal-gear-solid-hd → metal-gear-solid-hd-collection
• mgs-5-motherbase → metal-gear-solid-5-motherbase
• mgs-5-online → metal-gear-solid-5-online

There are also a few outstanding synonym requests on meta:

• Make metal-gear-series a synonym of metal-gear-solid-series (discussion)
• Make metal-gear-online-3 a synonym of metal-gear-solid-5-online (discussion)
