Fix Gleam lexer (#1072)

I made the Gleam lexer *dumber* (that is, more acquiescent), but it
fixes #1054 and still passes the tests.

chore: clean up Makefile

Add WebVTT lexer (#707) (#1032)

Implements a WebVTT lexer (#707)

lexers/cue: support CUE attributes (#961)

Currently the following CUE results in the chroma lexer producing an
error token for the '@':

    value: string @go(Value)

This code is, however, valid CUE. '@go' is an attributes.

This change adds lexer support for attributes in CUE.

fix: include compress state in style cache key

Fixes #945

Add renovate

fix: bad path normalisation

fix: attempt to load lexer files before using Get()

File loading runs after Get(), but Get() always succeeds so it would
never load a file.

Add test for ucode (#881)

Update Java lexer (#873)
