feat(neovim): upgrade kickstart neovim configuration (#128)

Besides upgrading `kickstart` configuration, the following changes were made:

* add `avante` to start working with `AI` code generation and reduce code boilerplate creation
* configure ide image/container with environment variables:
  * `NVIM_GIT_USER_EMAIL`: email associated with git commit
  * `NVIM_GIT_USER_NAME`: name associated with git commit
  * `NVIM_ANTHROPIC_API_KEY`: `anthropic` api key, used by `avante`
  * `NVIM_GH_TOKEN`: `github` token, used by `github cli`
