fix(extension-table): update selection position when inserting a new …

[wilson-everlaw]

…table

Typically when inserting a new table we want to select within the first cell of the newly inserted table. This change should ensure that occurs even if the original selection's head precedes the anchor.

fix #5143

Changes Overview

Using the selection's from instead of anchor is a better approach since the user may be making a selection where the head precedes the anchor

Implementation Approach

Changed the selection offset from tr.selection.anchor + 1 to tr.selection.from + 1

Testing Done

Made a selection from the end of the doc to the beginning, inserted a table and see that there is no error and that the selection is set to within the first cell.

Verification Steps

• Start with an empty editor
• Add content to the editor ensuring that it exceeds 44 characters
• Select the entire content starting from the end of the editor to the beginning of the editor to ensure that the selection's head precedes the anchor
• Insert a 3x3 table
• See that there is no error and that the selection is within the first cell
