document how to use SNAPSHOT versions

[bblfish]

version = "3.4.3+23-1483abef-SNAPSHOT"

When I try to use the latest SNAPSHOT because I want to use a new feature to test it,
I get the error

[error] (Test / scalafmtCheck) org.scalafmt.sbt.ScalafmtSbtReporter$ScalafmtSbtError: scalafmt: Invalid config: version [expected 3.4.3]: 3.4.3+23-1483abef-SNAPSHOT [/home/runner/work/Reactive-SoLiD/Reactive-SoLiD/.scalafmt.conf]

See the PR co-operating-systems/Reactive-SoLiD#21
and the errors generated by Continuous Integration.

I could not find any documentation on how to do this correctly.

@bblfish our recently updated issue template, which you're not following here, should have asked you to verify this problem with scalafmt CLI. it looks like you used the sbt integration instead, which might mean the problem is elsewhere.

If I update .scalafmt.conf with version = "3.4.3+14-e16384f2-SNAPSHOT"
Then run the following to get it to work

I get the same error with

If I then set the version in .scalafmt.conf to version = "3.4.3"
then I get...
Then it works...

[bblfish]

The commit above succeeded in using the matchSite features from #3126 with the command line interface

But I can't get it to work within sbt, so that my continuous integration tests don't pass.
Where should I report that?

[kitbellew]

if it works in CLI but not sbt plugin, then, obviously, in sbt plugin.

[kitbellew]

can you please try downloading (using coursier) a different version (take any published version from the last year), while specifying the desired snapshot version in the config file? does that work?

[bblfish]

can you please try downloading (using coursier) a different version (take any published version from the last year)

I tried two versions in my report above #3154 (comment)
was that not enough? (Or do you mean something else?)

[bblfish]

This change also fixed the sbt-plugin problem. See PR for httpSig
