Change search help text headings to h2

For Petitioning for Freedom I used this code - dropping it here so we can copy/paste.

In en.yml:

<h2 class="h4">Basic Search</h2>
<p>Simply enter the word you wish to find and the search engine will search for every instance of the word in the journals. For example: Fight. All instances of the use of the word fight will show up on the results page.</p>
<h2 class="h4">Wildcard Searches</h2>
<p>Using an asterisk (*) will increase the odds of finding the results you are seeking. For example: Fight*. The search results will display every instance of fight, fights, fighting, etc. More than one wildcard may be used. For example: *ricar*. This search will return most references to the Aricara tribe, including Ricara, Ricares, Aricaris, Ricaries, Ricaree, Ricareis, and Ricarra. Using a question mark (?) instead of an asterisk (*) will allow you to search for a single character. For example, r?n will find all instances of ran and run, but will not find rain or ruin.</p>
<h2 class="h4">Capitalization</h2>
<p>Searches are not case sensitive. For example: george will come up with the same results as George.</p>
<h2 class="h4">Phrase Search</h2>
<p>Searching for a specific phrase may help narrow down the results. Rather long phrases are no problem. For example: "This white pudding we all esteem".</p>
<h2 class="h4">Subsequent Searches</h2>
<p>Because of the creative spellings used by the journalists, it may be necessary to try your search multiple times. For example: P?ro*. This search brings up numerous variant spellings of the French word pirogue, "a large dugout canoe or open boat." Searching for P?*r*og?* will bring up other variant spellings. Searching for canoe or boat also may be helpful.</p>

In custom scss ($font-size-h4 variable is set in bootstrap-variables.scss):

.h4 {
  font-size: $font-size-h4;
}
