[Bug]: user's lsp config replaced the whole config rather than merge predefined config with overwrite.

Here's my config of pylsp to enable isort of pylsp
lua/user/lsp-servers/pylsp.lua:
return { settings = { pylsp = { plugins = { pyls_isort = { enabled = true }, }, }, }, }.
Due to the Steps to modify plugin configs part of the wiki, I think the table returned should just update the pyls_isort property but not replace the whole config.
