Require mcp 1.2.0 in the Ruby weather server

Browse source 
Protocol revision 2026-07-28 requires a resultType on every result. The mcp
gem stamps it as of 1.2.0, so a ">= 1.1.0" floor allowed an install whose
responses a 2026-07-28 client rejects outright.

Observed against the test client on 1.1.0:

  Invalid result for tools/list: missing required resultType

On 1.2.0 the same server lists both tools and both structured-content
assertions pass.
