Enable polling support for tailwindcss cli

[thebub]

Reasoning

Due to an WSL2 issue (microsoft/WSL#4739) the watch mechanism of the tailwindcss cli will not work on all potential developer setups. Especially when using vscode-devcontainers and keeping the code in the mounted directory. (assumed default behavior)
The recommended work around is to use polling instead of the normal inotify based watch mechanism.

Changes

• This pull request will add a new task to tailwindcss-rails to use the polling option instead of the watch option
• A parameter is added to the ./bin/dev script, to switch between watch and poll mechanism
• Default behavior of tailwindcss-rails remains unchanged

Waiting for TailwindCSS to ship the polling feature. The feature was omitted in the recent v3.0.24 release.

@thebub I have a new rails 7 application with tailwindcss installed. None of my CSS changes are reflected when reloading my pages. Is this a current limitation to working with WSL2? Or perhaps these issues are separate. Thanks.

@daveomcd I believe this is related to the wsl2 problem mentioned before, try moving your project files to your linux home folder (e.g. /home/daveomcd or ~) and see if the problem still happens

@daveomcd I suggest you follow the recommendation by @hyphenized and provide feedback, whether the problem is resolved or not.

Hey @thebub, thank you for the response. I figured out the issue I was seeing wasn't a problem with WSL2. It was because I ran rake assets:precompile by accident. To correct the problem I had I just needed to delete all the files in my public/assets folder.

I've created #199 which uses a task argument to implement this, which is a bit more flexible than a separate task (and can be combined with other options like debug from #198).

v2.0.13 has this feature, please see the README for an explanation.

Thanks @flavorjones. I wasn't aware of the possibility to add options as well. This is a way better solution!
