[FIX] beauty_parlor: prevent error when opening the Contact Us page

[fw-bot]

Currently, an error occurs when opening the Contact Us page.

Steps to Reproduce:

• Install the beauty_parlor with demo data.
• Go to Website > Contact Us.

ValueError: Element '<xpath expr="//section[@data-snippet='s_title'][1]/span">' cannot be located in parent view

This error started occurring in saas-19.1 after commit that reworked the Contact Us page to better
showcase the capabilities of the website builder. As part of that change, the section was modified,
but the code still references an XPath [1] that no longer exists in the main view. As a result, opening
the Contact Us page raises this error.

This commit replaces the default website aside image with a beauty parlor related image, similar to
what was done here, since the banner is no longer used in the main view.
