fix(highlight): add default flag to DiffsDiff* groups

Problem: DiffsDiff* highlight groups lacked default = true, making them
impossible for colorschemes to override, inconsistent with the fugitive
unified diff groups which already had it.

Solution: add default = true to all four DiffsDiffAdd, DiffsDiffDelete,
DiffsDiffChange, and DiffsDiffText nvim_set_hl calls.

HIGHLIGHT GROUPS *diffs-highlights*
diffs.nvim defines custom highlight groups. Fugitive unified diff groups use
`default = true`, so colorschemes can override them. Diff mode groups are
always derived from the corresponding `Diff*` groups.
diffs.nvim defines custom highlight groups. All groups use `default = true`,
so colorschemes can override them by defining the group before the plugin
loads.
All derived groups are computed by alpha-blending a source color into the
`Normal` background. Line-level groups blend at 40% alpha for a subtle tint;
