[🔥AUDIT🔥] Align variable names in SR strings for interactive graph (#…

…2131)

🖍 _This is an audit!_ 🖍

## Summary:

Our localization infrastructure requires that the names of the placeholders in the `strings` variable (the object with the English strings) matches the variable names in the same-named string generator function that appears in the `PerseusStrings` type.

This PR fixes two new strings so that their placeholder variable names match: `srRayEndpoint` and `srRayTerminalPoint`.

Issue: "none"

## Test plan:

Do another release and integrate it again and rerun the localization script.
