fix: 🐛 fix android soft keyboard dismisses when mark and input

[virgil1996]

Description
On Android, after toggling a mark (e.g. bold) with a collapsed selection, the next keystroke could dismiss the soft keyboard and break caret placement. The Android input manager scheduled a follow-up selection using a point computed as if the character were inserted inside the same text leaf (path unchanged, offset + text.length). When editor.marks is set, Editor.insertText uses insertNodes (a new marked text node) rather than extending the current leaf, so that computed point could lie beyond the leaf length and overwrite the valid selection that insertNodes had already applied.
This change stops scheduling a second Transforms.select with that raw point: performAction already normalizes action.at with normalizePoint and updates the selection; the previous run() callback duplicated the select with incorrect coordinates for the marks/insertNodes case.

Context
In handleDOMBeforeInput, after storeDiff for an insertion, the code called
scheduleAction(() => Transforms.select(editor, { anchor: newPoint, focus: newPoint }), { at: newPoint }). flush runs Editor.insertText for the diff; with active marks, Slate’s insertText inserts a new text node and sets the selection to the end of that node. performAction then runs: it first selects using normalizePoint(editor, newPoint), which maps an “past end of leaf” offset onto the correct following text node. Immediately after, action.run() called Transforms.select again with the un-normalized newPoint, which is invalid when the insert was a sibling node. Replacing the callback with a no-op keeps selection handling solely in the normalizePoint path inside performAction.
