chore: Update changelog generation for upcoming docs.
chore: update .mailmap to remove duplicate contributors
chore: make npm dependencies fixed

We are gonna depend on single version and test it.
This means we need to update deps manually, but it's not gonna break people.

feat(config): `browsers` can specify args and cmd

Support optional `cmd` and `args` parameters in the `browsers`
configuration. The `args` are appended to the default command-line
options for the browser. If `overrideArgs` is true, then the `args`
replace the default command-line options for the browser. Occurrences
of `$TEMPDIR` or `$URL` within the `args` are replaced by the temp
directory and URL. Use case is to pass special options, e.g., to
load browser extensions.

Closes #278
