Ensure radio/checkbox DOM IDs with float values are unique

[markedmondson]

Summary

Updates the DOM ID sanitizer for form input values so as to not cause potential duplicate values when using float values on a collection.

For example:

collection_check_boxes :user, :name, [1.0, 10], :to_s, :to_s

Returns:

<input type="hidden" name="user[name][]" value="" />
<input type="checkbox" value="1.0" name="user[name][]" id="user_name_10" />
<label for="user_name_10">1.0</label>
<input type="checkbox" value="10" name="user[name][]" id="user_name_10" />
<label for="user_name_10">10</label>

With this change:

<input type="hidden" name="user[name][]" value="" />
<input type="checkbox" value="1.0" name="user[name][]" id="user_name_1_0" />
<label for="user_name_1_0">1.0</label>
<input type="checkbox" value="10" name="user[name][]" id="user_name_10" />
<label for="user_name_10">10</label>

Fixes #34974
