Switch CI from travis-ci to GitHub actions

[andrew]

Also testing against a range of currently supported ruby versions, plus 2.7 for backwards compatibility.

Hi @andrew, I don't have much familiarity with github actions (or travis ci for that matter!) - I didn't add the initial continuous integration, that was @taichi-ishitani. What's the point of this switch - is it just that github ci is more integrated/easier to use?

I switched my CI flow from travis to GitHub Actions 4 years ago because travis was very slow at that time.

How about using the bundler-cache: true option of the setup ruby action like this?
https://github.com/taichi-ishitani/rupkl/blob/177f38d94116ef9b263c93fdf7eed717fba7d898/.github/workflows/ci.yml#L30

Then depdended gems will be installed automatically and so we can remove following 2 actions.

ruby-ole/.github/workflows/ci.yml

Lines 32 to 36 in 322923b

	- name: Install Bundler
	run: gem install bundler
	- name: Install dependencies
	run: bundle install

I’m on holiday this week, can add it when I get back or feel free to edit the branch yourself, I think I made it writable to admins

@taichi-ishitani I've updated ci.yml now to use bundler-cache: true, I also added a Gemfile so that bundler correctly installs all the test dependencies.

@aquasync travis ci's free option for open source has got significantly worse over the past few years, github actions is nicely integrated into the standard github workflow, it's also fast, free and unrestrictred for open source projects.

I also noticed a few deprecation warnings in the logs but I'll open seperate PRs for those once this is merged.

Ok thanks @andrew.

It doesn't seem to be running; looking at the config, is the issue that it mentions push/pr to "main" branch, whereas this repo has "master"?

yep, sorry my mistake, updated here: #30

Cool, yep that fixed it - thanks!
