fix(lualine): use the new ministarter file type to disable in mini.starter (#3929)

## What is this PR for?

`mini.starter` recently had a breaking change to set the file type to
`ministarter` instead of the old `starter`; so, `lualine` is enabled in
the dashboard because it's using the old file type.

## Does this PR fix an existing issue?

No.
