Support lsp-bridge in container correctly

[nohzafk]

Unify the logic for remote SSH file and docker file

When using find-file to open a file in container, the TRAMP buffer is now setup as the lsp-bridge buffer

• we treat the TRAMP buffer as a non-file buffer by setting buffer-file-name to nil
• previous impl is not correct (create a new buffer for docker file and close the corresponding TRAMP buffer)

Support apheleia formatter in container

Update README for how to setup PATH for remote command execution, otherwise the formatter binary won't be found (for example ruff, even it is installed in container)

Support find defition in container

Support using lsp-bridge-find-def lsp-bridge-find-def-return lsp-bridge-find-def-other-window in container.

Text Matrix

lsp-bridge-find-def-select-in-open-windows	docker file	lsp-bridge-find-def/-return	lsp-bridge-find-def-other-window
nil	yes	pass - jump to another file and jump back pass - jump to current file and jump back	pass - open a new window
nil	no	pass - jump to another file and jump back pass - jump to current file and jump back	pass - open a new window
t	yes	jump to opened window - pass	pass - jump to opened window
t	no	jump to opened window - pass	pass - jump to opened window

issue

Under current implementation if jump to other window, lsp-bridge-find-def-return can't jump back to original window. It would be nice if we support jump back to original window.

lsp-bridge user must be install Nix?

[nohzafk]

container support is done by using the devcontainer feature which use nix to install lsp-bridge and language server.

I'm planing to create a separate repo for instructions and setup of how to use lsp-bridge in container. Will update README to point to the new repo later.
