Work In Progress: Update dependencies and Dart SDK in workflows

[UnHumbleBen]

Testing Dart CI workflow by triggering it through this pull request

Description

Updated dependencies in response to OverReact upgrade to version 4.2.6.

scadnano workflows will now use Dart SDK 2.13 instead of 2.9 because Dart SDK 2.9 is no longer supported by OverReact. Dart SDK 2.13 is the newest SDK supported by OverReact because newer versions rely on analyzer 1.x, which OverReact does not support as noted in the OverReact workflow file.

react_components_test_template.html has been updated in response to upgrading test_html_builder from version 1 to version 2.

Lastly, to ensure that our developers are working on the app with the exact same versions, I committed the pubspec.lock file. This is recommended for application packages, as noted in the Dart documentation.

How Has This Been Tested?

• Ran unit tests locally
• Run Dart CI workflow
• Run github-pages-dev workflow on fork
• Run github-pages workflow on fork
• Have @dave-doty test out the changes by pulling this branch and see if he can still run webdev serve and unit tests.

Do you think we should change this line:

environment:
  sdk: '>=2.9.0 <3.0.0'

to

environment:
  sdk: '>=2.11.0 <3.0.0'

Since OverReact is going to require >=2.11 anyway?

[dave-doty]

I am able to rub locally after running

pub get

then

webdev serve

Unit tests (running ./tests.sh) also pass.

It's annoying that we still get the analyzer warning:

But it appears that OverReact is still requiring the old version of analyzer:

@dave-doty Updated SDK requirement in pubspec.yaml and fixed and tested the Github workflows, as indicated above. Ready to merge as soon as changes are approved.
