85: Add resouce count to change summary

[tfitch]

Change

Update for issue #85 to add the number of changed resources or outputs to the summary reports.

Note

This did not get linted because when I installed golanglint-ci it was a newer version (2.1.2) and wanted to update the .golangci.yaml file. I'll leave that to you.
Directly running go test passes.

Hi @dineshba I'll try and get this sorted out this weekend. What was my one line in writer/html_test.go got completely refactored when that whole section of validating my change was removed in https://github.com/dineshba/tf-summarize/pull/97/files#diff-c4ae7acd1d29d7303351ffc50b955eb57ad7763bbc9e3a96cc5ae4f4d7eead58L12

So I don't trust doing the browser based conflict review, I'll have to get on my personal laptop and do the full test and validation with the latest from the main branch.
I could accept the latest from main but then there's no validation of my change in the HTML output which is less than ideal. So if I can, I'll find a new validation.
