MWPW-142563: Add Eager Loading to LPC Image for Blog

[JasonHowellSlavin]

• Adds loading: eager and fetchpriority: high to blog.

Context: There was never a large difference in the PSI scores when testing. However, I am hoping that this will get us more in line with Brand Blog and we will see CrUX scores benefit from the change.

Resolves: MWPW-142563

FYI the default is already eager.

The difference you are going to see with fetchpriority is if there are multiple eager loading images.

high
Fetch the image at a high priority relative to other images.
