Modernize git-log-parser

[AbhiPrasad]

From examining semantic-release, I found that git-log-parser is a good opportunity for us to modernize.

https://npmgraph.js.org/?q=git-log-parser

Primarily it brings in traverse, which I think it doesn't need to, but there is also an opportunity to ESMify it and rely more on built-in Node APIs.

1.1 mil weekly downloads - great impact radius.

I've created bendrucker/git-log-parser#7 which removes traverse. Modernizing it further will be a breaking change, but I think semantic-release is the only major package that depends on it.

@valadaptive your changed updated semantic-release from:

110 MB / 493 dependencies

to

94 MB / 427 deps

still lot's to go, but amazing work!!!
