Fix doc_markdown DevOps false positive

This fixes an issue where the word "DevOps" ends up as a false positive for the `doc_markdown` lint.

In a doc comment like this
```rust
/// Call the Azure DevOps REST API.
pub fn example() {}
```
the word "DevOps" is highlighted as something which should be in backticks.
```
warning: item in documentation is missing backticks
 --> src/lib.rs:1:20

This could be overriden with the `doc-valid-idents` configuration parameter as noted by the [documentation](https://rust-lang.github.io/rust-clippy/master/index.html#/doc_markdown), but I believe the word "DevOps" is sufficiently common to belong alongside exceptions like "GitHub" and "GitLab".
