fix(util.lsp): pass formatters_by_ft to opts (#6894)

## Description
Here
c64a61734f/lua/lazyvim/util/lsp.lua (L50)
we call directly `conform.format` with our specific options.

`conform.nvim` also allows passing options such as `lsp_format` directly
to `formatter_by_ft` as also can be seen
[here](5420c4b5ea/doc/conform.txt (L20-L21)).
Those options are not passed when we call `conform.format(opts)` in the
LSP formatter.

So, we add these options. Also, fix the correct name for general format
options, since it had been changed at some time in `conform.nvim` and
that change made it to the plugin spec, but not here.
