github workflows needs name correction according to the job

[MrJithil]

In our repository, we typically name GitHub workflow files as the job name if only single job exists or some meaningful names, but some files do not follow this naming convention and its hard to identify what exactly it does without checking the file.

Below changes needed.

File Name	Rename to
.github/workflows/doc.yml	.github/workflows/build-docs.yml
.github/workflows/daily.yml	.github/workflows/build-lto.yml

Need a suggestion here. Not sure, are we referencing this files directly using the file names.

If we are good to go with this, please mark it as good first issue

cc @nodejs/build

Please feel free to close the issue if its not necessary now to rename.

+1 for build-doc, Im not sure what build-lto stands for

The first rename sounds good but the second one will create confusion for someone new. What is the job of the second file?

I'd like to work on this issue. I'll start by analyzing the current workflow files and then make the necessary renames according to the convention discussed.
