feat: Add adaptors for ollama and openai

[noahbald]

Adding adaptors here, as per huggingface/llm-ls#40

Unfortunately I have been unable to get this to work, as the commands in downloadAndUnzip do not seem to work on my windows machine.

If someone is able to try this on a unix machine and check if it is functional would help in getting this forward

@noahbald I am new to this work. Can you please provide documentation on how to test this and I can give it a try on my machine.

Hey @YasirFarhan I reckon @McPatate will be able to help you out. For me to get this set up, I did the following

• Follow the instructions for developing a plugin, using Gradle to run an instance of Intellij with the plugin
• Pull my fork of llm-ls, from here (https://github.com/noahbald/llm-ls)
  • Use Cargo to build the project
• Configure your instance of the llm-intellij plugin, setting the binary path to your build of llm-ls
