Allow to set the version of the unittest plugin

[camalot]

accept input for unittest-version

if not set, it will use the default "latest" version.
if it is set, specify that version during the install of the plugin

Thank you for working on this, @camalot! Could you add a test case in the CI workflow for this, however? I understand there is incompatibility between versions 0.2.x and 0.3.x of helm-unittest, but maybe as a test case we could try installing 0.3.3 and checking that that is the version that was installed?

I'm thinking we could always let the action itself fail, as is done in existing test scenarios, and just check the version afterwards. What do you think?

[camalot]

Sure thing. I will look into that. I had to throw a quick fix together today as a lot of our repos started failing the other day, and i just tracked it down today to being the most recent build of helm-unittest (related issue: helm-unittest/helm-unittest#219)

we have been using this action up until when v0.3.5 was released without issue.

I will probably have some time tomorrow to take a look at adding tests around it.

[camalot]

ok, so i had a few minutes...

here is what I was thinking after looking at the existing test cases.

  test-action-unittest-version:
    name: Unittest Version
    runs-on: ubuntu-latest
    timeout-minutes: 10

    steps:
      - name: Checkout repository files
        uses: actions/checkout@v3
      - name: Run composite action
        uses: ./
        with:
          github-token: ${{ secrets.GITHUB_TOKEN }}
          unittest-version: v0.3.4
          
      - name: Check that helm-unittest is installed
        run: helm plugin list | sed 1d | awk '{print $1}' | grep -q '^unittest$'

      - name: Check that helm-unittest version is v0.3.4
        run: helm plugin list | sed 1d | awk '{print $2}' | grep -q '^v0.3.4$'

verify that it is installed, and the specified version is installed.

That looks good to me, feel free to commit it. If it doesn't run automatically, I'll approve the workflow here so we can see how it behaves. Thanks, @camalot!

[d3adb5]

Ah, Helm doesn't prefix versions in the plugin table with v, that's why it failed. The fix is simple, luckily.

[camalot]

yeah, i also tweaked it to include the name of the plugin, just in case. didnt want to have it "pass" if there was some other plugin that had the version.

[d3adb5]

Left two suggestions, but otherwise looks good to me! Would you be so kind as to squash your commits and follow conventional commits, @camalot?

[camalot]

I think i squashed correctly. its been awhile.

and I think the commit message follows the Conventional Commits.

[camalot]

I should probably update the readme as well...

I will get to that tomorrow.

[d3adb5]

I took the liberty of updating the README and removing trailing whitespace. Thank you, @camalot! I'm merging this for now and creating a new release.
