Rewrite calculator supported constants

[ghassanmas]

So in calcualtor examples tables in list some constants that are no longer supported:

frontend-app-learning/src/courseware/course/content-tools/calculator/Calculator.jsx

Lines 257 to 266 in 61f0ce2

	<FormattedMessage
	id="calculator.instruction.table.to.use.constants"
	defaultMessage="Constants"
	/>
	</th>
	<td dir="auto">c, e, g, i, j, k, pi, q, T</td>
	<td dir="auto">
	<ul className="list-unstyled m-0">
	<li>20*c</li>
	<li>418*T</li>

In calcuator V3 some constants are removed, hence: openedx/openedx-calc@5e75af6

Also this might lead to affiex tip to not work as expected, so may be this also need to be removed:

Thanks for bringing this to my attention @ghassanmas. I was able to find the original PR that removed some of the constants, at openedx/openedx-platform#17368

The constants k, c, T, and q were all causing user confusion and leading to unnecessary forum posts and support tickets. Support was removed, so they should also be removed from these examples.
