deps: bump chisel and scala

[eastonman]

Chisel 6.4.0 has released https://github.com/chipsalliance/chisel/releases/tag/v6.4.0

Also bump scala because I encounter a scala compiler bug in JDK 21.
scala/bug#12783
This is fixed in 2.13.11+

[poemonsense]

Is this Scala version still compatible with Chisel 3.6.0?

[eastonman]

No, unfortunately, chisel3-plugin is released up to scala 2.13.10

[eastonman]

I will remove the Scala version bump in this PR.
I believe JDK 17 is still considered "modern" now?

[eastonman]

Unfortunately, for some reason, scala 2.13.10 cannot compile under JDK 17 either.
Do we now have to deal with two Scala versions?

[Tang-Haojin]

Maybe you can have a try :)

It works on my environment with JDK 17, Scala 2.13.10, and Chisel 3.6.0

[eastonman]

OK, I notice there is an issue with my JDK. JDK 17 seems ok now.
