Have the board refresh when new techs are discovered.

[jonoruss2]

One thing I've noticed when playing (a lot) of this game, is that when I get a new technology, the board doesn't update the game icons. So if I roll and get "Industrial Tech", the factories all look the same, unless I reload the board by saving/reloading or increase/decrease the icon sizes. This is fine but also kinda annoying after awhile.

This can be fixed (and I've verified this), with a single line of code in game-app/game-headed/src/main/java/games/strategy/triplea/ui/TripleAFrame.java :
this.mapPanel.resetMap();

on line 912.

It's possible that a better option might be to put this one line in with the lambda expression above it, in the ifPresent area.

I've been playing it with this change for awhile, and it works great. It passes all the tests, and passes formatting validation.
I tried doing a pull request, but it says I'm not a "contributor". I'm not sure how I become one, and, honestly, this is a lot of paperwork for a single line of code.

So instead, I'm just going to drop it in the feature requests/ideas box.

I do not see any PR from you @jonoruss2
Could you link it here, then I would review the change and merge it.

I was unable to create a PR, partially because I don't know what I'm doing. When I try to create a pull request, it makes me select a subdirectory, so I use "updates", and when I try to create a PR it gives me this error:
"Pull request creation failed. Validation failed: must be a collaborator"

How do you try to create the PR, @jonoruss2?
I think instead, you should fork the repository and open a pull request from your fork. See https://github.com/triplea-game/triplea/blob/main/docs/development/README.md#getting-started
Thank you for reporting the bug and trying to fix it! 👍
