In README.md, clarify the location of chat/ folder for compiling tabnine chat.

It took me way too long to find this folder. Hope I'll save someone else the time.

We can add :TabnineChatBuild command. @aarondill wdyt?

[aarondill]

@amirbilu
that could work. what would you expect it to do? just run cargo build?

if we're doing that, should we also (or instead) add a :TabnineBuild command to run dl_binaries?

[amirbilu]

great idea!

[aarondill]

@amirbilu and @christian-oudard, I'm in favor of adding commands like :TabnineChatBuild to make this process easier for users, but I don't think this PR should be merged, as this files location is different depending on the user's package manager.

if you think differently, I can create a (collapsible) section in the readme describing the location for the most popular package managers (Lazy.nvim, packer, vim-plug, native packages, etc).

Please let me know which you think is the better approach here.

Is there anyway this Readme addition could be added in the meantime? It took me far too long to realise I needed to do it from here instead of just cloning the repo and running the cargo build --release command that way

Also for Lazy, the directory would be:

~/.local/share/nvim/lazy/tabnine-nvim/chat
