Update lspconfig, add indent-blanklineHEADmaster

indent-blankline is probably old because I've actually been using it for
ages, but I have a strict if-it-ain't-broke policy, so I'm not going to
update it.

lspconfig *was* broke though with nvim 0.10, so now it's fixed.

+Lean installation instructions can be found
+[here](https://leanprover-community.github.io/get_started.html#regular-install).
+
+Once Lean is installed, you can install the Lean 3 language server by running
+```sh
+npm install -g lean-language-server
+```
+
+Note: that if you're using [lean.nvim](https://github.com/Julian/lean.nvim),
+that plugin fully handles the setup of the Lean language server,
+and you shouldn't set up `lean3ls` both with it and `lspconfig`.
