Error: lspconfig_to_mason is nil when using mason.nvim v2.0.0

[Beep6581]

After updating to mason.nvim v2.0.0, I encountered the following error when starting nvim:

Error executing vim.schedule lua callback: ...on-tool-installer.nvim/lua/mason-tool-installer/init.lua:141: attempt to index field 'lspconfig_to_mason' (a nil value)

Steps to Reproduce:

1. Update mason.nvim to v2.0.0.
2. Ensure mason-tool-installer.nvim is at its latest commit.
3. Start nvim, which throws an error related to lspconfig_to_mason being nil.

This issue likely arises due to API changes in mason.nvim v2.0.0 that are not yet accounted for in mason-tool-installer.nvim.
