chore: bump version to 1.2.0

Bump the project version and the places that restate it:

- build.gradle, which names the published artifact
- README installation snippet and changelog, in both the erb template
  and the generated README.md
- SerpApiHttp.VERSION, which had drifted to 1.0.0 while the project was
  at 1.1.0. It is public and never read anywhere in the library, so the
  stale value was only ever visible to callers.

demo/build.gradle still pins 1.0.0 and is left alone, since it resolves
a published JitPack artifact rather than this source tree.
