Fix some typos in `orth` names

[nkprasad12]

As per page 133 (antistrophe) and 205 (augurius), there are meant to be breves instead.

@nkprasad12 Thank you for all of this excellent work.

For future reference, if there is an obvious error in the print and we wish to correct in this version, the tags should be:

<choice><sic>print version</sic> <corr>corrected version</corr></choice>

This avoids silent corrections.

Please let me know if you wish to be added to the header for your contributions.

Thanks for the feedback, @lcerrato ! I just wanted to clarify - I don't see any <choice> tags currently in the document, but I do see some <reg> tags that contain <sic> and <corr>. Should stick to <reg>, or use <choice> here?

[lcerrato]

@nkprasad12 I have not reviewed this tagset (I did not work on this text at all) so we use <choice> the primary text collections now, but as those use a different schema, that could account for any differences. If there is precedent for <reg> that's certainly fine with me.

Anything that steers clear of silent corrections.

@lcerrato

For consistency, I've added <reg> for the two typo fixes; see 98a58c6

@nkprasad12 Thanks!
