merge revision(s) 72eb33066fa9e7dacb7470cd140b219abe37667e: [Backport #19320]

	Fix off-by-one error in rb_vm_each_stack_value

	Applying the following patch to test/erb/test_erb.rb and running that
	file will cause Ruby to crash on my machine (macOS 13.1 on M1 Pro):

	```
	--- a/test/erb/test_erb.rb
	+++ b/test/erb/test_erb.rb
	@@ -7,6 +7,12 @@
	 class TestERB < Test::Unit::TestCase
	   class MyError < RuntimeError ; end

	+  def setup
	+    GC.auto_compact = true
	+    GC.stress = true
	+    GC.verify_compaction_references(expand_heap: true, toward: :empty)
	+  end
	+
	```

	It crashes with the following log:

	```
	/Users/peter/src/ruby/lib/erb/compiler.rb:276: [BUG] Segmentation fault at 0x00000001083a8690

	/Users/peter/src/ruby/build/ruby(gc_rest) ../gc.c:9570
	```

	This crash happens because it's reading the VALUE at sp. But since
	sp points to the top of the stack, it's reading the VALUE above the
	top of the stack, which is causing this segfault.

	Fixes [Bug #19320]
