[MOOSE-325] Masthead Search Icon

[GeoffDusome]

What does this do/fix?

This pull request improves the way the search icon SVG is loaded in the masthead-search block to make it more robust and reliable. Instead of directly fetching the SVG using a URL, it first tries to read the file from the file system and falls back to a remote request only if necessary. This is a similar approach we took while grabbing the theme.json file in the Block Editor Custom Alignments plugin.

Improvements to SVG loading:

• The code now attempts to load the SVG icon from the file system using file_get_contents and only falls back to using wp_remote_get if the file read fails, ensuring better reliability and compatibility across environments.
