Potential fix for code scanning alert no. 43: Inefficient regular expression

[rjohnson2011]

Potential fix for https://github.com/department-of-veterans-affairs/vets-json-schema/security/code-scanning/43

To fix the issue, we need to rewrite the regular expression to remove the ambiguity caused by overlapping matches. Specifically, we can replace the ambiguous [-a-zA-Z0-9/']+( ?) with a more precise pattern that explicitly matches a sequence of valid characters followed by an optional space. For example, we can use [-a-zA-Z0-9/'](?: [-a-zA-Z0-9/'])* to ensure that spaces are only allowed between valid character sequences, not at the end.

This change will preserve the original functionality while avoiding exponential backtracking. The fix should be applied to all instances of the problematic regex in the file.
