Smarter matching: when typed chars are exactly matched against entries, put them first

[zjp-CN]

Current:

Wanted: Period first

[zjp-CN]

As of zjp-CN/nvim-config@e31b935 , put score comparator first can solve this.

local compare = require("cmp").config.compare

opts.sorting.comparators = {
        compare.score, -- add this
        comparators.inscope_inherent_import,
        comparators.sort_by_label_but_underscore_last,
}

Documention should be improved.
