Fix malformed Markdown table row for codeVerifier

Line 1373 is missing a properly terminated 4th cell, causing markdownlint MD055/MD056 warnings. This can break rendered docs/table alignment in some viewers.

Suggested fix 
- **codeVerifier** | **string** |  | 
+ **codeVerifier** | **string** |  |  |

In `@internal/httpclient/docs/OAuth2API.md` at line 1373, The markdown table row
for codeVerifier is missing the trailing cell separator; update the table row
for "codeVerifier" (the row showing **codeVerifier** | **string** |  |) to
include the fourth cell delimiter by adding a trailing pipe so the row has four
cells properly terminated, ensuring the table aligns and fixes markdownlint
MD055/MD056 warnings.
