Update package.json

Slight re-wording of the description to solve the problem with it cutting off due to exceeding the character limits by 6 characters

Changed one instance of "and" to an ampersand (&), removed "to VS Code" (wasn't really needed as this only shows within the VSCode Marketplace, and wouldn't be any benefit to SEO)

Changed "latest" in the LLMs selection, to "best" - this gives a better "feeling" than "latest" as the latest LLM could be a tiny 1b parameter model which means nothing for Cody.
