Update buildpack metadata in buildpack.toml (#189)

Adjusts the buildpack `name`, `description` and `keywords` in
`buildpack.toml` to match the style discussed in:
heroku/cnb-builder-images#408

These fields are used by the CNB registry and can also be seen in the
output of `pack builder inspect`. They are not used by `pack build` or
Kodon.
