Welcome Guide Help Modal: Spelling and Capitalization Issues

[kathrynwp]

Description

When editing page via the Site Editor, a welcome guide modal window appears, with some copy issues I noticed:

1. The spelling "customise" is incorrect for someone whose site is set to US English – the WP default language – where the customary spelling is "customize."
2. "Site Editor" is usually capitalized, whereas here it's just "site editor."

Step-by-step reproduction instructions

1. Go to Appearance > Editor
2. Click Pages in the left sidebar
3. Click one of the pages in the list
4. Click in the right-hand preview area
5. Observe welcome guide modal

I've got a PR that updates these two sections of copy - #53028

"Site Editor" is usually capitalized, whereas here it's just "site editor."

I've seen it both ways quite a bit — is there a standard here? I know patterns, templates, template parts, command palette, block editor are all lowercase; any reason why site editor shouldn't be? cc @WordPress/gutenberg-design

I'd lean towards not capitalizing. While site editor is a useful term to refer to the section, in fact it's called "Design" in the main title. This is in part due to how things might evolve in the future, where in fact all of WordPress is your Site Editor, proper-noun-capitalized, and Design is just a section of that. I do agree it's important to be consistent.
