feat: remove unused code (#260)

Remove a lot of unused code, related to:

* **Support for older versions of `elixir`**:
  * Remove `openssl` 1.1
  * Remove `elixir-ls` repository
  * Remove script to install pinned versions of `elixir-ls`
* **Unused tools from `mise`**:
   * `aqua:CircleCI-Public/circleci-cli`: This isn't my `ci/cd` service of choice.
   * `aqua:xo/usql`: Even though this is interesting, I mainly interact with the default tooling of the databases.
   * `go:github.com/bloznelis/typioca`: I go for the `tukai` or `ttyper` to improve my keyboard profecience
   * `pipx:vectorcode`: I've never really used it.
     * In this case, I also removed the `neovim` plugin and `mcp` server.
   * `ubi:block/goose`: I go for the `opencode`, or the specialized tools, such as `claude-code` or `gemini-cli`.
   * `ubi:supabase/cli`: I've never really used it.
   * `poetry`: I changed to `uv`.
