Remove SCL reviewers/approvers from OWNERS_ALIASES

[nikhita]

For kubernetes/org#2013

To adequately leverage the SCL reviewers/approvers list in OWNERS_ALIASES,
we would need to add multiple OWNERS files in various directories.
Otherwise, the bot ends up suggesting reviewers and approvers from
other parent directories.

To avoid this complexity, remove the list of SCL reviewers/approvers
from OWNERS_ALIASES.

Original commit message below.

---

As a part of cleaning up inactive members (who haven't been active since
the release of v1.11) from OWNERS, this commit removes lukemarsden from
the SIG Cluster reviewers/approvers list.

i don't think these owner aliases are serving their purpose properly at k/website.

the approver list is not something that is used because the only approvers in this repo are sig-docs owners.
none of the listed reviewers of SIG CL are active in reviewing PRs in this repository.

my vote goes for removing these owner aliases.

Would SIG Cluster Lifecycle like to nominate a new set of reviewers for the relevant sections?

I'm also fine with removal.

[neolit123]

i don't think the bots will pick people from the SIG CL list, unless we add OWNERS files in the appropriate locations.

as seen in some PRs against SIG CL maintained docs:
#22150
#21663
#22083
#22070

the bots pick different reviewers from a potentially parent OWNERS file.
which creates a question mark for the existing of the SIG CL owner alias in its current state.

also looking at https://github.com/kubernetes/website/blob/9e87d15493c2606feba44fa322a3baa0e51c327e/OWNERS_ALIASES
SIG CL is the only non-sig-docs alias, so +1 for removal.
