```
sed -z -i 's/Author: /Authors: /' bip-0*.md
sed -z -i 's/Author: /Authors: /' bip-0*.mediawiki
```
Also align correctly in case of multiple authors.
```
sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.md
sed -z -i 's/Type: Standards Track/Type: Specification/' bip-0*.mediawiki
```
After the scripted changes, the changes to BIP-40, BIP-41, and BIP-63
were undone, because it breaks CI.
These three BIPs only exist conceptually and their proposal documents
are missing which causes changes to them ot break the CI. I defer the
changes to these BIPs to a separate pull request to get CI to pass.
Amend CI script to new statuses and update existing status field values
in table and BIPs.
```
sed -z -i 's/Status: Proposed/Status: Complete/' bip-0*.md
sed -z -i 's/Status: Proposed/Status: Complete/' bip-0*.mediawiki
sed -i 's/| Proposed/| Complete/' README.mediawiki
```
