Fix links to CSP list initialization algorithms

The spec as a whole is written in en-GB-x-hixie, but this is the name of
an algorithm, similar to InitializeHostDefinedRealm, so do not use
data-x="..." to change the spelling in the prose.

The "Initialize a global object's CSP list" algorithm is actually
unused.
