fix launch configs: use com.ibm.icu

[Eskibear]

replace com.ibm.icu.base with com.ibm.icu, otherwise below error occurs:

Thanks @Eskibear

See PR #1362, looks like com.ibm.icu is not required by the runtime any more, right? @fbricon

[fbricon]

unfortunately, it's still required by platform and JDT. We just ensured it's not a direct dependency of jdt.ls, until the time both platform and jdt drop it too.

ok, got that. thanks.
