nlp doc change

[arnavk23]

Removed outdated call to finalize(nlp) and recommended using the CUTEstModel("PROBLEM") do nlp ... end syntax for automatic cleanup as mentioned #275, thus this Closes #442.

• Also want to add that we don't need a tutorial.md when the contents of the file is an introduction video and it is already mentioned on the readme.md file.

Did you try CUTEstModel{Float64}("CHAIN") do nlp ... end in a terminal to check if it works.
I am at the airport but these other terminals will not help us to find the issue :)

[arnavk23]

@amontoison I think now this will pass all the checks.

Thank you @arnavk23 !
I will merge the PR if all tests passed.
