Description

When using craft\web\Request->accepts(), we should account for subtype wildcards in accepted content types.

With changes in this PR:

• if getAcceptableContentTypes() contains "application/*" and you’re checking accepts('application/json'), the results should be true
• if getAcceptableContentTypes() contains "application/json" and you’re checking accepts('application/*'), the results should be false
• if getAcceptableContentTypes() contains "application/json" and you’re checking accepts('application/json'), the results should be true
