Describe the solution you'd like

I would like a provides option, that stops packages with the same name from being installed, as long as they aren't dependnecies.

How it would look:

return {
    {
	"stevearc/conform.nvim",
        provides = "nvimtools/none-ls.nvim"
    },
    {
	"williamboman/mason.nvim",
	dependencies = {
		"WhoIsSethDaniel/mason-tool-installer.nvim",
		"jay-babu/mason-nvim-dap.nvim",
		"williamboman/mason-lspconfig.nvim",
		"RubixDev/mason-update-all",
               "jay-babu/mason-null-ls.nvim",
		"nvimtools/none-ls.nvim" -- being installed, MAYBE also prevents conform.nvim from being installed, except if it has the "bypass_provides" option, set to true
        },
    },
    {
        "rebelot/heirline.nvim",
        provides = "nvim-lualine/lualine.nvim"
    },
    {
        "hrsh7th/nvim-cmp",
        provides = { "Shougo/ddc.nvim", "saghen/blink.cmp", "neoclide/coc.nvim"  }
    },
    {
        "nvim-java/nvim-java",
        provides = { "mfussengger/nvim-jdtls"  }
    },
    {
        "mfussengger/nvim-jdtls" -- not being installed
    },
}

Describe alternatives you've considered

I haven't considered anything, since it's adding a spec option...

Additional context

That should be everything!
