Fix 341291: Enter key does not work after an inline entity under a list

[JiuqingSong]

Repro:

<ol start="1"><li><div style="margin: 0px;">test <span class="entityDelimiterBefore" style="font-family: Calibri; font-size: 11pt; color: rgb(0, 0, 0);">​</span><span class="_Entity _EType_OWALink _EId_OWALink _EReadonly_1" contenteditable="false"><span>ENTITY</span></span><span class="entityDelimiterAfter" style="font-family: Calibri; font-size: 11pt; color: rgb(0, 0, 0);">​</span></div></li></ol><!--{"type":"range","start":[1],"end":[1],"isReverted":false,"isDarkMode":false}-->

Press ENTER.

Expect: Go to next line and generate list item "2."
Actual: Nothing happens

This is in entityDelimiter code, it incorrectly retrieve the parent block using a wrong index.
Actually, when parent block group type is ListItem, we should not handle it since it will be handled by common enter handler code

• [nitpick] The change to use path[0] assumes that the first element of the path is always the intended parent block. Please verify that this index reliably represents the correct parent in all cases, and consider renaming the variable to reflect its specific role if needed.

selectionBlockParent = path[0];
