fix: 'Apply' in 'Create or edit Task' started failing earlier today

[claremacrae]

Description

Downgrade esbuild from 0.14.43 to 0.13.15.

esbuild 0.14.0 was a breaking change, so go for the last release on 0.13.x for now.

Motivation and Context

Fixes #764: Clicking 'Apply' in 'Create or edit Task' fails with console error.

How has this been tested?

1. Edit the rebuild version
2. Delete node_modules
3. yarn install
4. yarn dev
5. Copy the created files to my test vault
6. Restart Obsidian
7. Confirm that the Apply button now works as expected
