Add support for {date} replacement

[BelKed]

Resolves #30.

• Added date replacement
• Better formatting in actions.yml + Added option for date format
• Updated readme.md

[fregante]

There are a lot of unrelated changes (the action.yml formatting isn’t “better” and is unrelated) and the file in distribution should not be modified manually. The source is /index.js. Please ensure that exclusively changes related to dates are included in this PR.

• Oh, I will move edits to /index.js. I wondered why index.js in distribution had so many lines – I think, that was file, I should edit.
  • Also, shouldn't be it in .gitignore and builded and committed by Github Action on push/pull request?
• And I have to fix bug, where longer or shorter dates caused bad date, hash and title of commit in description.

• There should be updated documentation with building/contributing/developing...

shouldn't be it in .gitignore and builded and committed by Github Action

Unfortunately this doesn’t work with GitHub Actions. They want a pre-built file committed to the repo.

Also no need to force push. Just add commits normally.

Can you also add some tests to ensure it works?

Can you also add some tests to ensure it works?

And how?
I tested it in on my private repo and date option works...

[fregante]

There’s a file that ends with .test.js. Look at how the other features are tested a create similar tests for this new option. It should test for both a keyword and some custom formats

[BelKed]

I added date test, but after I run it it except a error on generates changelog with custom date presets. It's function with test custom date format. I don't know what is wrong with it.

[fregante]

Perfect, thanks! I’ll leave it here a day or 2 and then merge it if no one complains

[BelKed]

I added more date formats, especially for the date without leading zero and also for testing in generate-release-notes.test.js... It's using dateformat.

[fregante]

Please undo, git date formats are good enough.

Also no need to force push. Just add commits normally.

Apart from the minor nits, looks good to me.

[BelKed]

I remade whole test, because custom date format check is failing. It was failing because generateReleaseNotes function does not run git log with custom date parameters...

[fregante]

Not a bad idea, I dislike mocks for this exact reason, they give a false sense of security.

[BelKed]

Could you merge this pull request now, so I can open another, that fixes another issue?

[fregante]

Thank you @BelKed!

Unfortunately the commit titles aren’t being excluded from the replacement. The commit here included {date} and was replaced with the actual date.
