fix(vim.version): fix metatable for intersections #41615

Browse Source 
Problem:
`vim.version.intersect()` returns tables with `VersionRange` (method
table) as their metatable. Although the calculated bounds are correct,
the results do not expose `VersionRange` methods.

Solution:
Construct intersection tables with `range_mt`, matching
`vim.version.range()`. Add assertions covering method access and
repeated intersection.
