deps: v8 will require ICU 63

[srl295]

When https://crbug.com/v8/8401 lands in Node.js, ICU ≥63 will be required. Looks like v8 may not check the version properly.

see also nodejs/node#24253

Something like the following (not sure of the newline situation)

diff --git a/tools/icu/icu_versions.json b/tools/icu/icu_versions.json
index e17ee8beee..7224e9debe 100644
--- a/tools/icu/icu_versions.json
+++ b/tools/icu/icu_versions.json
@@ -1,3 +1,3 @@
 {
-    "minimum_icu": 57
-}
\ No newline at end of file
+    "minimum_icu": 63
+}

looks like v8/v8@30a350f

v8 is tracking this in
https://crbug.com/v8/8424 to make the requirement clear.
