clangpdb-ci.yml: Fix string replacement (#552)

String replacement did not occur as expected with nunjucks. The
yaml/json formatted strings were not treated as raw strings as expected,
resulting in unexpected formatting of inputs.

## Example of Incorrect formatting:

### Example 1:

In this example, both the python version and package config inputs need
to be wrapped in quotes

/>

### Example 2:

In this example, package config value replacement value needed to be
treated as a raw string, so the `|` was used

/>
