fix(navic): use the same background color as lualine section_c (#4231)

## Description

Prior to this, when using the navic Extra, the symbol breadcrumbs shown
in lualine section_c had a background color different from the
background of lualine_c, causing it to standout and not blend in with
some colorschemes.

There were ways around this problem, but hose involved overriding a lot
of highlights. See https://github.com/LazyVim/LazyVim/issues/328

This change uses the new (as of April 2023) lualine component built in
to SmiteshP/nvim-navic, which has a `color_correction` option to fix the
problem described above. This built-in component replaces the manual
method of calling `require("nvim-navic").is_available()` and
`require("nvim-navic").get_location()`.

With `color_correction` set to "static" or "dynamic", navic uses the
lualine section's background color when building the breadcrumbs text.

I chose to set color_correction to "dynamic" to provide the best user
experience as that will update the background any time the lualine
section's background changes (e.g. when switching modes).

section_c's:

After this fix, the breadcrumb's background does match:
