Small copy edit for Evaluation Tools List

Hey, I didn't quite know how to do a pull request for this, but I think the tooltip for the filter "Accessibility statement" is missing an apostrophe for "tools":

Current: <img alt="Vendor provided information on tools accessibility" data-toggletip-content="Vendor provided information on tools accessibility"...>

Proposed: <img alt="Vendor provided information on tool's accessibility" data-toggletip-content="Vendor provided information on tool's accessibility"...>
